We changed email regex patterns in one place to Angular built-in, but kept our own regex in another place. We may change both?

Describe the bug

We changed email regex patterns in one place to Angular built-in, but kept our own regex in another place. We may change both?
Previously changed email regex pattern:
#4999

Stil remaining DSpace’s own email regex pattern for the feedback form:

dspace-angular/src/app/info/feedback/feedback-form/feedback-form.component.ts

Line 58 in 444edd4

email: ['', [Validators.required, Validators.pattern('^[a-z0-9._%+-]+@[a-z0-9.-]+\\.[a-z]{2,4}$')]],

Expected behavior

We should validate all email address input fields identically and get rid of custom regex code.

@MW3000 Agree, this sounds very reasonable!
