PRs generated from a fork cannot run check_release as of now

• We need to separate the branch parameter into ref (the source reference) and target (the target branch) since the branch does not exist on the target repo.
• We cannot make draft GitHub releases because we have a read-only token. Technically we can run the workflow on the forked repository but it would not be visible to a reviewer of a pull request.
• So, check_release needs to be modified to build assets, check them, and publish them (using the local pypi server and npm --dry-run, and bypass any GitHub release activity.
