9cef7a4600Backport #25171 by @silverwind The plan is that all built-in auth providers use inline SVG for more flexibility in styling and to get the GitHub icon to follow `currentcolor`. This only removes the `public/img/auth` directory and adds the missing svgs to our svg build. It should map the built-in providers to these SVGs and render them. If the user has set a Icon URL, it should render that as an `img` tag instead. ``` gitea-azure-ad gitea-bitbucket gitea-discord gitea-dropbox gitea-facebook gitea-gitea gitea-gitlab gitea-google gitea-mastodon gitea-microsoftonline gitea-nextcloud gitea-twitter gitea-yandex octicon-mark-github ``` GitHub logo is now white again on dark theme: <img width="431" alt="Screenshot 2023-06-12 at 21 45 34" src="https://github.com/go-gitea/gitea/assets/115237/27a43504-d60a-4132-a502-336b25883e4d"> Co-authored-by: silverwind <me@silverwind.io> Co-authored-by: wxiaoguang <wxiaoguang@gmail.com>
