Refactor setting.Other and remove unused SHOW_FOOTER_BRANDING (#24270)
The `SHOW_FOOTER_BRANDING` came from year 2015, and it seems nobody ever
uses it. It only shows an GitHub icon which seems unrelated to Gitea, it
doesn't do what document says. So, remove it.

## ⚠️ Breaking

Users can now remove the key `[other].SHOW_FOOTER_BRANDING` from their
app.ini.
