Special characters are not allowed in email addresses

[dtroelofsprins]

What version of EMX2 are you using (see footer)
v11.13.0

Describe the bug
It's not possible to include email addresses which include special characters, f.e. elż[email protected]

To Reproduce
Steps to reproduce the behavior:

1. Go to 'https://emx2.dev.molgenis.org'
2. Click on pet store (or create a new schema using the pet store template)
3. Go to the User table
4. Create a new user with email address ü[email protected] => At first glance it seems OK, because no error is shown
5. Only when saving the data the following error is thrown:
   Update into table 'User' failed.: Transaction failed: Validation failed: ü[email protected] is not valid EMAIL

Expected behavior
Except from "@" every character should be possible to use before the @ (it may even be case-sensitive)
The shortest valid email address could be i@me

Additional context
Your E-Mail Validation Logic is Wrong
