docs: reformat and update CONTRIBUTING.md (#37951)

I also updated a few sections, since they were either poorly written or obsolete.

1. Be sure that an issue describes the problem you're fixing, or documents the design for the feature you'd like to add.
Discussing the design upfront helps to ensure that we're ready to accept your work.
1. Please sign our [Contributor License Agreement (CLA)](#cla) before sending PRs.
We cannot accept code without this. Make sure you sign with the primary email address of the Git identity that has been granted access to the Angular repository.

If you have more than one Git identity, you must make sure that you sign the CLA using the primary email address associated with the ID that has been granted access to the Angular repository. Git identities can be associated with more than one email address, and only one is primary. Here are some links to help you sort out multiple Git identities and email addresses:
