Simplify e-mail address regex
Description
The regex in user.rb is probably one of the better ones, everything I'd expect to validate validates. However, I'd still propose it's removed, or refactored to simply be /@/.
First, some reasoning: https://davidcel.is/posts/stop-validating-email-addresses-with-regex/
Second, with RFC5322, UTF-8 is now permitted on modern servers. 甲斐@黒川.日本 is a valid e-mail address.
Also, the 60 length limit is not found in any RFC.

I agree on removing the validation or replacing it with a check for the "@" symbol.
I was doing some reading on this, and one common recommendation is to send the user a test email to validate there email address. This might not be something that applies to all cases, and is much more involved then simply checking during a UI field, but if we really wanted to make sure an email address worked, it might be worth considering.
