Fix issue with creation of GitHub release caused by missing cli switch

Reference: #1307

The command added, `gh release create`, fails without the `--repo` siwtch. This change adds it.

Here is an Action run that fails without it https://github.com/uclahs-cds/BL_Python/actions/runs/6658063247/job/18094142825

And a successful Action run that succeeds with it. https://github.com/uclahs-cds/BL_Python/actions/runs/6658181985/job/18094515444
