Launch tracking

Edit this issue to keep track of the tasks you're working on towards launch.

We have a rough guide for how to launch a track, which is sorely outdated but
quite possibly better than nothing (I'm so sorry, I'm waaaay behind on getting
documentation updated).
https://github.com/exercism/docs/blob/master/language-tracks/launch/README.md

Check out https://github.com/orgs/exercism/teams/track-maintainers/discussions/1
for details about the #maintainers channel in the exercism-team Slack workspace.

Please ask if you have any questions or if anything is confusing!

Start with language-tracks/launch/README.md, the rough launch guide linked in the issue, and the track-maintainers discussion for the launch process and questions. Review the repository's current state against that guidance; done is not defined beyond progressing the Shen track toward launch and updating this tracking issue.
