(cherry picked from commit 609a627a44dbcb7b630ff51ce9f4b9f448b48ca8)

Conflicts:
	- docs/content/administration/config-cheat-sheet.en-us.md
	- docs/content/administration/config-cheat-sheet.zh-cn.md
	  Removed both, they're Gitea specific.
	- templates/base/footer_content.tmpl
	  Applied the change manually, keeping the Forgejo footer.
