Use the new preview screen when tapping media on the room and pinned events screens. (#3736)

* Use the new TimelineMediaPreview modifier on the room and pinned timeline screens.

* Use the same presentation logic for all timeline media previews.

* Fix a bug with the detection of the timeline end.

* Send pagination requests from the media preview screen.

* Add SwiftLint to the Danger workflow (it is no longer installed on the runner).

* Put SwiftLint back on all of the GitHub runners too.

* Set the function_parameter_count lint rule to 10.

* Make sure to clean-up any previews when the coordinator is done.
