How should we improve Contributing.md?

We've had a recent wave of issues and pull requests that feels to me like it's not in the spirit of improving this project, rather something completely random or a change that's just for the sake of change.

Here's some examples
Issues
- https://github.com/firstcontributions/first-contributions/issues/106812
- https://github.com/firstcontributions/first-contributions/issues/106772
- https://github.com/firstcontributions/first-contributions/issues/106645

Pull requests
- https://github.com/firstcontributions/first-contributions/pull/106768
- https://github.com/firstcontributions/first-contributions/pull/106717
- https://github.com/firstcontributions/first-contributions/pull/106706
- https://github.com/firstcontributions/first-contributions/pull/106775
- https://github.com/firstcontributions/first-contributions/pull/106822

I'm wondering if improving our [Contributing.md](https://github.com/firstcontributions/first-contributions/blob/main/.github/CONTRIBUTING.md) can improve this.

Maybe details like
- Check for `help wanted` label before starting on a issue
- Make sure maintainers confirm before making changes to Readme
- If you're submitting an issue, think about how this improves this project. Explain it in the issue
