We should move the https://github.com/wikimedia/svgtranslate Git repository from GitHub to Wikimedia's GitLab. Some reasons:

• Keep all our codebases together within Wikimedia.
• Avoid contributors having to give their data to external services.
• Better integration with Phabricator.

Steps to take:

• Create new repo https://gitlab.wikimedia.org/toolforge-repos/svgtranslate
• Copy main branch of GitHub repo to the new one
• Set up CI https://gitlab.wikimedia.org/toolforge-repos/svgtranslate/-/merge_requests/1
• Reconfigure Translatewiki.net to write to the new repo: T404491
• Check all open PRs and move any that are still needed
• Update GH repo with a link to the new location
• Archive the GitHub repo
• Update all documentation and other links (Wikitech etc.)
• Make sure everyone who needs it has access (especially L10n-bot)
• Update prod and test servers to point to the new repo
