chore: update readme

[Keyrxng]

Resolves #317

This is a simple edit as the DB is not required for 99% of feature requests. Unless you think it's necessary to also include DB schema.

Those are long h1 headers you sure you want to do it that way?

It's inside a code block so it's standard comment syntax

Great can you make sure that the entire readme is up to date with everything that needs to be there beyond just Supabase if anything? Then you can merge thanks.

[Keyrxng]

I can't think of anything else that it needs really beyond the /beta branch info but that's handled on that branch.

I added the legacy env vars NONCE and NONCE_SIGNER_ADDRESS which are used in the invalidation script but that's not used anymore is it? Or is that how you invalidate permits still?

The reason we only have two previews instead of three here is because the first hit a bad gateway error which is unrelated to the current CI deployment issue.

Further confused by it because it appeared like core team could deploy, but whilefoo's last two attempt against /beta failed similar to other contributors. It only seems to work for me, you and rndquu...

rndquu just fixed it yesterday so hopefully we see more reliability
