fix: validation password

[GeorgKott]

password validation has error when email doesn't contain the @ symbol

[paulbalandan]

How can an email address not contain the @ symbol?

How can an email address not contain the @ symbol?

Because we check the email for a valid value and then check the password with the same email value, even if the email is invalid. And any value can be sent from the frontend

@GeorgKott Thanks to PR.

Please answer these questions?

1. Do you use service('passwords') directly?
2. Why not use defined rules for email validation?
   

   shield/src/Config/AuthSession.php

   Lines 26 to 35 in 35fcaaa

   	/**
   	* The validation rules for email
   	*
   	* @var string[]
   	*/
   	public array $emailValidationRules = [
   	'required',
   	'max_length[254]',
   	'valid_email',
   	];

If the email is invalid, wouldn't the validation fail and complete at that point?
Please write test code to reproduce that error.
