Suggested solution

Add support using jj binary, just like it is done for git.

Alternative

Don't support jj, leave that to a fork.
jj can't create git tags yet and it is still indev so commands may change, so jj support may be a noticeable maintenance burden.

Additional context

Currently I have resorted to using this command to publish new releases:

cd (mktemp -d) && git clone <url> . && npm install && npm run release && rm -rf (pwd)
