ci: Minor reorganizations

[LecrisUT]

• [x] Removed concurrency where it wasn't necessary. Only top-level workflow needs it
• [x] Harden the CI workflows
• [x] Reorganize workflow order
• [x] Update actions. Normally dependabot is used to update these actions (also node/python dependencies) but the dependabot PRs can get quite noisy. Do you want it to be setup though?
• [ ] Setup a full release CD
  • Slightly blocked by: https://github.com/re-actors/alls-green/issues/25
  • The workflow would be more complicated and would require re-converging the version numbering, let's do this in a next step
• [x] Reconfigure codecov action
  • Relaxed the upload to codecov to only occur in PR and when pushing
  • This is a rather weird issue, maybe it's some race condition or the fact that it is run through a fork. Hopefully in v4 this is resolved: https://github.com/codecov/codecov-action/issues/1138 https://github.com/codecov/codecov-action/issues/1035 https://github.com/codecov/feedback/issues/112
• [x] Other minor improvements
