Custom regexp external issues (#17624)
* Implement custom regular expression for external issue tracking. Signed-off-by: Alexander Beyn <malex@fatelectrons.org> * Fix syntax/style * Update repo.go * Set metas['regexp'] * gofmt * fix some tests * fix more tests * refactor frontend * use LRU cache for regexp * Update modules/markup/html_internal_test.go Co-authored-by: Alexander Beyn <malex@fatelectrons.org> Co-authored-by: techknowlogick <techknowlogick@gitea.io> Co-authored-by: Lauris BH <lauris@nix.lv> Co-authored-by: 6543 <6543@obermui.de> Co-authored-by: wxiaoguang <wxiaoguang@gmail.com>
