* Fix alignment of RTL messages
Inspired by https://github.com/matrix-org/matrix-react-sdk/pull/5453 but
hopefully with the edited marker in the right place.
This is a PoC: types aren't correct and the style needs pulling
out to a class. Plus it would probably need more visual tests added.
If this looks acceptable, I can make these changes.
* Fix spacing between text and edited annotation
* Update snapshot
* Update more snapshots
* More snapshots
* More more snapshots
* Split out style
* Fix emotes
This will cause them always be right-justified if the display name
is rtl.
* Add playwright test for ltr/rtl message rendering
* Better snapshots
* Await on message sending
* Better waiting, hopefully
* Old snapshot files
* Really hopefully fixed screenshots this time
* Don't include the message action bar in the screenshots
