feat: update and sync runners (ubuntu-22.04, macos-14)

This commit does two things:

- Updates our Ubuntu runner (used for x86 Linux builds) to
  `ubuntu-22.04` instead of `ubuntu-20.04`. GitHub is in
  the process of sunsetting their `ubuntu-20.04` image. For
  now, dist hasn't changed the default runner for
  `x86_64-unknown-linux-gnu`, so we're overriding it here.
- Syncs the runner used for Apple Silicon macOS builds
  across dist and regular CI testing to always use
  `macos-14`. Previously, dist would use `macos-13`, which
  is x86 macOS, and cross compile to ARM. This didn't
  match what we did in our own regular CI testing. Now
  they match, which should hopefully reduce the chance of
  surprise errors at release time in the future.
