Background

As it stands, beginner users must add the Supabase functionality manually to use Supabase.

What does this PR do?

his PR allows for them to simply add their SUPABASE_URL and SUPABASE_ANON_KEY to the .env to use supabase as their db.

What kind of change is this?

Improvements (misc. changes to existing features)

Why are we doing this? Any context or related work?

As a user it is very difficult to use the Supabase adapter. This makes it much easier for a beginner user to not have to code any new functionality to use the adapter. In conjunction with #203 the user can simply add their SUPABASE_URL and SUPABASE_ANON_KEY to the .env to use supabase as their db.

I also would like to update the documentation that is at https://eliza.gg/eliza/docs/packages/adapters/ under Schema Management, PostgreSQL Schema. The Sql is incorrect and causes errors. I have the correct sql that ran on Supabase without error. When i look at the docs on the main branch of this repo. The lines that need edited do not exist. Where can i make this change?
