Link to sign_up view appears when project "Allow new users to sign up" is disabled

Bug report

Describe the bug

In Supabase, I have disabled sign-up in the project settings via option "Allow new users to sign up".

However, when users want to sign-in for the first time, some are confused and click on the "Don't have an account? Sign up" link, and of course when they hit "Sign Up" it does not work for them, which normal.

To Reproduce

Use any supabase app, use Auth component.

Expected behavior

The "Don't have an account? Sign up" link should not appear when project does not allow sign-ups.

Or at least, it should be customizable.
