Fix changelog versions

We do this by a) not pulling out all membership events, and b) batch
inserting bans.

One blocking concern is that this bypasses the `update_membership`
function, which otherwise all other membership events go via. In this
case it's fine (having audited what it is doing), but I'm hesitant to
set the precedent of bypassing it, given it has a lot of logic in there.

+# Synapse 1.135.2 (2025-08-11)
+
+This is the Synapse portion of the [Matrix coordinated security release](https://matrix.org/blog/2025/07/security-predisclosure/). This release includes support for [room version](https://spec.matrix.org/v1.15/rooms/) 12 which fixes a number of security vulnerabilities, including [CVE-2025-49090](https://www.cve.org/CVERecord?id=CVE-2025-49090).
+
+The default room version is not changed. Not all clients will support room version 12 immediately, and not all users will be using the latest version of their clients. Large, public rooms are advised to wait a few weeks before upgrading to room version 12 to allow users throughout the Matrix ecosystem to update their clients.
+
+Note: release 1.135.1 was skipped due to issues discovered during the release process.
+
+Two patched Synapse releases are now available:
+
+* `1.135.2`: stable release comprised of `1.135.0` + security patches
+    * Upgrade to this release **if you are currently running 1.135.0 or below**.
+* `1.136.0rc2`: unstable release candidate comprised of `1.136.0rc1` + security patches.
+    * Upgrade to this release **only if you are on 1.136.0rc1**.

+
+Pre-built wheels are now built using the [manylinux_2_28](https://github.com/pypa/manylinux#manylinux_2_28-almalinux-8-based) base, which is expected to be compatible with distros using glibc 2.28 or later, including:

+# Client-Server API Extensions
+
+Server administrators can set special account data to change how the Client-Server API behaves for
+their clients. Setting the account data, or having it already set, as a non-admin has no effect.
+
+All configuration options can be set through the `io.element.synapse.admin_client_config` global 
+account data on the admin's user account. 
+
+Example:
+```
+PUT /_matrix/client/v3/user/{adminUserId}/account_data/io.element.synapse.admin_client_config
+{
+    "return_soft_failed_events": true
+}
+```
+
+## See soft failed events
+
+Learn more about soft failure from [the spec](https://spec.matrix.org/v1.14/server-server-api/#soft-failure).
+
+To receive soft failed events in APIs like `/sync` and `/messages`, set `return_soft_failed_events`
+to `true` in the admin client config. When `false`, the normal behaviour of these endpoints is to
+exclude soft failed events.
+
+Default: `false`

+The arguments passed to this callback are:
+
+* `user_id`: The Matrix user ID of the user (e.g. `@alice:example.com`) making the request.
+
+If the callback returns a dictionary then it will be used as the body of the response to the
+client.
+
+If multiple modules implement this callback, they will be considered in order. If a
+callback returns `None`, Synapse falls through to the next one. The value of the first
+callback that does not return `None` will be used. If this happens, Synapse will not call

+# Ratelimit callbacks
+
+Ratelimit callbacks allow module developers to override ratelimit settings dynamically whilst
+Synapse is running. Ratelimit callbacks can be registered using the module API's
+`register_ratelimit_callbacks` method.

+may change without notice.
+</span>**
+
+Called when constructing a ratelimiter of a particular type for a user. The module can
+return a `messages_per_second` and `burst_count` to be used, or `None` if
+the default settings are adequate. The user is represented by their Matrix user ID
+(e.g. `@alice:example.com`). The limiter name is usually taken from the `RatelimitSettings` key
+value.
+
+The limiters that are currently supported are:
+
+- `rc_invites.per_room`
+- `rc_invites.per_user`
+- `rc_invites.per_issuer`
+
+The `RatelimitOverride` return type has the following fields:
+
+- `per_second: float`. The number of actions that can be performed in a second. `0.0` means that ratelimiting is disabled.
+- `burst_count: int`. The number of actions that can be performed before being limited.

+If multiple modules implement this callback, they will be considered in order. If a
+callback returns `None`, Synapse falls through to the next one. The value of the first
+callback that does not return `None` will be used. If this happens, Synapse will not call
+any of the subsequent implementations of this callback. If no module returns a non-`None` value
