[docs] Fix broken links and typos (#4418)

# Description

Fix links and typos in docs and settings page:

* Fix https://codeberg.org/superseriousbusiness/gotosocial/issues/4328
* Fix https://codeberg.org/superseriousbusiness/gotosocial/issues/4360

Also fix broken issuetracker links as forgejo does not support search
queries like "label:bug"

The translation for Zh-cn still says "this project" according to google
translate, I only fixed the link.
