Add updated Firefish migration docs
This MR adds a new documentation section in the migration docs for Firefish v20241205, which is the latest version of Firefish as of this writing. Many thanks to @dakkar for helping me figure this out on the Discord server!
Some notes:
- The original section for v1.0.5-RC is still present. Instead of replacing it, I added the version to the heading and created a new one for v20241205.
- Antennas from this version of Firefish use an apparently different storage format for the
excludedKeywords
column. As I don't have enough data to figure out how to migrate this properly, I added a warning callout stating that they're incompatible and should be recreated, and truncated the table in the SQL.
