[Bug] Fix the email validation in Contact page

[NidhiTornekar]

Description

The contact section does not have correct validation for the email field.
In below example, even an incorrect email such as "test@gmail" was accepted.

I wish to fix the regex for correct validation.

Please assign me this issue under gssoc.
