Updated README.md for clarity
The current README.md file provides little information about what this repo is for, especially for users who find this repo without knowing about GrapheneOS. This updated version provides a brief description with helpful links to other related issue trackers. Ideally work could be done to fully flesh the README.md file, but this is a step forward.
There are more issue trackers listed at https://grapheneos.org/contact#reporting-issues but some are probably missing there now. This should at least have all of those.
The "About" section for this repo should be updated as well.
Do any more edits need made?
The About message for the repo should be changed now that this has been merged.
Changed in what way?
Saying "Standalone projects like Auditor, AttestationServer and hardened_malloc have their own dedicated trackers." is redundant to what is already in the README, and only lists a few of the many projects, so it isn't very useful anyways.
It's not redundant since it might be all people read. Going to leave it as is.
