"SSH / GPG Keys" settings point to GitHub docs instead of Codeberg#940

Repeating what I mentioned [on Mastodon](https://fosstodon.org/@neatnit/109865943396657326), since I searched for older issues and found none. Go to SSH / GPG Keys: https://codeberg.org/user/settings/keys and you'll see links to GitHub doc pages:  Codeberg has its own docs for these topics: https://docs.codeberg.org/security/ssh-key/ Adding an SSH key to your account https://docs.codeberg.org/security/gpg-key/ Adding a GPG key to your account (There is no equivalent of GitHub's [troubleshooting page](https://docs.github.com/en/authentication/troubleshooting-ssh), though, from what I can tell) It would be nice if Forgejo pointed to these instead of GitHub. I looked a little deeper, and I believe the source of this text is: https://codeberg.org/Codeberg/forgejo/src/branch/codeberg-1.18/templates/user/settings/keys.tmpl the template for the entire Keys page https://codeberg.org/Codeberg/forgejo/src/branch/codeberg-1.18/templates/user/settings/keys_ssh.tmpl#L100 ([permalink](https://codeberg.org/Codeberg/forgejo/src/commit/1f31b235b813e58939a0b4565ab173e1f34180be/templates/user/settings/keys_ssh.tmpl#L100)) the template for the SSH section, inserting the linked URLs https://codeberg.org/Codeberg/forgejo/src/branch/codeberg-1.18/templates/user/settings/keys_gpg.tmpl#L112 ([permalink](https://codeberg.org/Codeberg/forgejo/src/branch/codeberg-1.18/templates/user/settings/keys_gpg.tmpl#L112)) the same for the GPG section https://codeberg.org/Codeberg/forgejo/src/branch/codeberg-1.18/options/locales/gitea_en-US.ini#L662-L663 ([permalink](https://codeberg.org/Codeberg/forgejo/src/commit/1f31b235b813e58939a0b4565ab173e1f34180be/options/locales/gitea_en-US.ini#L662-L663)) the localization strings, for en-US Note, of course, that all 30 localizations would need to be updated if the links are changed.
