Add a workflow for publishing to itch.io

Do you have an opinion on using https://github.com/marketplace/actions/butler-push instead of doing it manually?

Would it be possible to reuse the builds uploaded to the release tag instead of rebuilding?

AFAIK if we use the action we'll have to write it separately for each channel. By doing it manually, I can use a for loop.

There is always an option of using a matrix, but this seems... wasteful?

Actually in my usecase I was not rebuilding because I was not using the release tag at all - I ran only this workflow. itch.io was my distribution platform, not GitHub.

If we want to tie this to the tag release workflow, then I think it would be too cumbersome to make the user trigger this from the GitHub UI, since they'll have to wait for the release to finish before doing so and since they'll have to manually pick the tag from the combobox. Instead, I think it'd be better to add another job to release.yaml and making it not run if the user did not set env.itch_target.

If we do that, we can also use the tag name for butler's --userversion flag.

I think I would prefer that. You could also add a env variable to disable deploying to GitHub release if you want?

This would mean the regular release cycle will have to use artifacts in addition to deploying to the GitHub release. I'm... not sure I see the advantage in that.
