gotosocial: update to version 0.7.1

ChangeLog (taken from https://github.com/superseriousbusiness/gotosocial/releases/tag/v0.7.1):

v0.7.1 Even Stormier Sloth
adb5966

Hello hello! This is a small bugfix release for Stormy Sloth!
Highlights:

    /about page
    new postgres installations actually work now
    png thumbnails preserve transparency
    oob token requests will redirect to the correct page, showing the token
    small api fixes to make 'role' property on accounts more mastodon-api compatible
    don't perform storage cleanup on startup (should alleviate issues where people were having to wait three minutes for their instances to start up)
    code is now 90% gayer and anti-capitalister

Migration notes

If you're migrating from 0.7.0 you don't really have to do anything special at all! If you're migrating to 0.7.1 from a previous version, check the release notes for 0.7.0 :)
