Added
* Added `allow_contact_info` config option to specify whether personal names
and avatars for other users should be bridged.
* The option is only safe to enable on single-user instances, using it
anywhere else will cause ghost user profiles to flip back and forth between
personal and default ones.

fails.

Improved
* Updated Docker image to Alpine 3.17.
* Updated to Telegram API layer 152.
* Improved handling users getting logged out.

login codes on the official mobile clients now.

Fixed
* Fixed handling Telegram chat upgrades when backfilling is enabled.
* Fixed file transfers failing if transfering the thumbnail fails.
* Fixed bridging unnamed files with unrecognized mime types.
* Fixed enqueueing more backfill.
* Fixed timestamps not being saved in `telegram_file` table.
* Fixed issues with old events being replayed if the bridge was shut down
uncleanly.
