Update dependabot, actions, and the readme. (#976)

* Test on the latest macos-14 runners.

These should be faster than the current macos-latest.

* Automatically update GitHub actions versions with dependabot.

Adjust dependabot PRs to a weekly schedule with a limit on the active PRs to reduce noise.

* Mention the discussion board in the README.

* Use latest github actions versions.

* Switch back to macos-latest on failing builds.
