Add Mastodon 4.1.2 (2023-06-26)

[jaller94]

Fixes #2543.

Note, I'm not sure if I want to maintain this Docset long-term, but it seems valuable.

There's a repo with all the build steps (including Gitlab CI instructions) and mayyybe I'll update it once a year - no promises.

I don't know what the error message means.

The docset's docSet.dsidx is empty (the SQLite database doesn't contain any entries).
