[TEMPLATE] sync with package template

[zacharyburnett]

Resolves SCSB-257

adds an update.yml workflow from the STScI package template that runs every Monday and checks for new updates to the upstream template at https://github.com/spacetelescope/stsci-package-template. If new commits are found on stsci-package-template@main, this workflow makes a new pull request to THIS repository applying the diff.

Tasks

• If you have a specific reviewer in mind, tag them.
• add a build milestone, i.e. Build 12.0 (use the latest build if not sure)
• Does this PR change user-facing code / API? (if not, label with no-changelog-entry-needed)
  • write news fragment(s) in changes/: echo "changed something" > changes/<PR#>.<changetype>.rst (see changelog readme for instructions)
    • if your change breaks step-level or public API (as defined in the docs), also add a changes/<PR#>.breaking.rst news fragment
  • update or add relevant tests
  • update relevant docstrings and / or docs/ page
  • start a regression test and include a link to the running job (click here for instructions)
    • Do truth files need to be updated ("okified")?
      • after the reviewer has approved these changes, run okify_regtests to update the truth files
• if a JIRA ticket exists, make sure it is resolved properly
