chore: Rename missing-commits job, and combine nix job files (XRPLF#5268)

- Rename the job in missing-commits.yml from "check" to "up_to_date",
  because other jobs named "check" prevent merges, but this one should
  not prevent merges. How else are branches going to get caught up?
- Move the job in instrumentation.yml to nix.yml, but keep it entirely
  independent.
