Build GHA development practice

### Overview
We need org level GHAs across projects, and it would be useful to have some general HfLA guides about GHAs so that we can make running projects easier.

### Action Items
- [ ] Identify where the open GHAs will live
- [ ] Review how the Data Science Community of Practice shares opportunities with their members
- [ ] How we will determine prioritization
- [ ] Who can submit
- [ ] Requirement drafting standards

- https://github.blog/changelog/2022-01-21-share-github-actions-within-your-enterprise/

Start by reviewing the linked admin issue, open-source-automations issue, and GitHub Actions sharing announcement. Use the action items to document the proposed location, prioritization process, submission rules, and requirement-drafting standards. Done means the organizational practice and accompanying HfLA guidance are defined, with the open questions resolved.
