What is your suggestion?

To make things easier for Kevin and I (and all users who want to submit a PR), we should write a PR template similar to our Issue templates that makes gathering the minimum information simpler.

We likely want to write a PR template using the info from this website: https://docs.github.com/en/communities/using-templates-to-encourage-useful-issues-and-pull-requests/creating-a-pull-request-template-for-your-repository

Also can look at the template text used by the jwst repo:

<!-- If this PR closes a JIRA ticket, make sure the title starts with the JIRA issue number,
for example JP-1234: <Fix a bug> -->
Resolves [JP-nnnn](https://jira.stsci.edu/browse/JP-nnnn)

<!-- If this PR closes a GitHub issue, reference it here by its number -->
Closes #

<!-- describe the changes comprising this PR here -->
This PR addresses ...
