1. Create a validations.ts file under the common folder
2. Implement email and password validations:

src/app/common/validations.tsimport { Validators } from '@angular/forms'export const EmailValidation = [Validators.required, Validators.email]export const PasswordValidation = [  Validators.required, Validators.minLength(8), ...
