[Invalid]: Issue with useValidate params

[risv1]

Description

Uhh I did an oopsie doopsie, useValidate shouldn't depend on any Auth specific params, it should only take in the validator schema, but "vibes" added params like isSignUp and stuff into it. Make validator functions offered by the hook purely modular to be designed to work in any form submission scenario. You can fix this in any future feature addition, just tag this issue when you do :)
