Currently, the EmailValidator only provides the full 'value' in the params
dictionary when a ValidationError is raised. However, in many use cases,
developers need to customize error messages based specifically on the
domain part of the email (e.g., "The domain %(domain_part)s is not
allowed").
This change adds 'domain_part' to the params dictionary in
EmailValidator.__call__, bringing it in line with how other validators
provide decomposed parts of the validated value. This allows for more
granular and helpful error messages for end users.
I have already prepared a patch with tests and verified that it passes all
style (flake8) and functional checks.
