## What kind of change does this PR introduce?
Bug fix. Resolves
[FE-4264](https://linear.app/supabase/issue/FE-4264/hide-social-sign-in-options-after-email-sign-up).
## What is the current behavior?
After a successful email and password sign-up, GitHub and ChatGPT
sign-in options remain visible even though they do not confirm or link
the new account.
The success state is presented in a bespoke `Alert` with verbose
copywriting.
## What is the new behavior?
The social sign-in options and divider are hidden after email sign-up
succeeds. The email confirmation message and link back to sign in remain
available.
The success state is presented in a standard `success` `Admonition` with
clearer copywriting.

## To test
1. Open `/sign-up` and complete an email and password sign-up.
2. Confirm the success message is shown without the GitHub, ChatGPT, or
`or` options.
3. Open `/sign-in` and confirm GitHub and ChatGPT remain available
there.
