Update dependency org.matrix.rustcomponents:sdk-android to v26.2.6 (#6144)

* Update dependency org.matrix.rustcomponents:sdk-android to v26.2.5

* Fix breaking API changes:
- Add temporary imlementation for `RustClientSessionDelegate.onBackgroundTaskErrorReport`, logging unrecoverable errors in background tasks of the SDK.
- Change `TimelineEventTypeFilter` to `TimelineEventFilter`.
- Support new `LatestEventValue.RemoteInvite`.

* Update the Rust SDK to `26.2.6`

* Fix API changes: `TimelineFocus.PinnedEvents` no longer takes any arguments

* Fix test fixtures: `NotificationItem` has a `rawEvent` field now
