Migrating from xyz.maubot.rss

Rough notes on migrating

• Start by watching logs: docker logs --follow CONTAINER_NAME
• Backup your db from maubot's data directory. Note file ownership. For me it was 1337:1337.
• Delete the instance and plugin from maubot manager.
• Restore db to original location with same file ownership.
• Upload dev.miguelr.rssbot .mbp file.
• Create new instance with same ID you had before. Should see schema update in docker logs.
• Enable both client and instance.
• If client is not responding in matrix rooms, shell into container and use mbc auth to get new access token and device ID and update the client in maubot manager.
