Email field on `/users/sign_in` is misleading

[asavageiv]

If I type alan+3@test.com into the email field and click "Sign In" but select alan+42@bettertest.com then I will be signed in as alan+42@bettertest.com. One of the benefits of Passkeys is that users don't even need to type their email address. What do you think about removing the field there?
