Deleting passkeys with incorrect password redirects users to passkey registration page

Steps to reproduce:

• On https://staging-ref.gitlab.com/ navigate to account settings and register a passkeys, or navigate to an existing registered passkey.
• Use the delete icon to delete the passkey, but when prompted to confirm password, type in incorrect password
• The UI will navigate to the register passkey UI, instead of an error message indicating the error.

Expected

We show a validation error like we do for WebauthN deletion.
