Add a PR template

[mozzieongit]

We had previously talked about forgetting to update the man page configuration when adding or removing pages; and now worry about forgetting to run the integration tests. This PR template would serve as a reminder for anyone opening PRs.

---

• If you are changing Rust code or integration tests (Cargo.*, crates/, etc/, integration-tests/, src/):

  • Did you run the integration tests with act through the act-wrapper (as described in TESTING.md)?

• If you are adding/deleting man pages:

  • Did you update the man_pages config in doc/manual/source/conf.py?
  • Did you update the packaged man pages in the Cargo.toml?

I don't know if the

(Cargo.*, crates/, etc/, integration-tests/, src/)

is helpful or distracting.

Nice. Man pages also need to be make man'd to generate the final man page, should that be part of this list too? Or should they be generated prior to release/packaging? Or even ideally by packaging?

[Philip-NLnetLabs]

We have the generated man pages in git. So ideally they should be part of a PR when the documentation is changed.

Perhaps CI can check whether make man causes changes / seems out of date?
