CI - Reduce when package job runs (#4539)

# Description of Changes

We run the "package CLI" job for every `master` commit, but I think we
basically never use those. Instead I added the work flow dispatch option
which can run as a one off if needed. (I didn't test it, but now that
it's added, we'll be able to fix it in a PR if needed).
