Subject: [PATCH] docs: Remove unexposed extensions (#46686)

removes three extensions from the list on the Postgres Extensions docs
page because we do not expose those extensions to users. extensions
removed are: amcheck, pg_surgery, pg_freespacemap

also adds a small cosmetic change to clarify that "public" refers to the
`public` schema on the same documentation page

## I have read the
[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)
file.

YES

## What kind of change does this PR introduce?

docs update

## What is the current behavior?

extensions are listed at
https://supabase.com/docs/guides/database/extensions that will result in
permissions errors should users try to install them themselves, as they
require superuser access to install

## What is the new behavior?

removes those items from the list

 If you need to restrict user access to tables managed by extensions, we recommend creating a separate schema for installing that specific extension.
