Symfony version(s) affected: 5.x.x (probably even previous versions)

Description
https://github.com/symfony/Validator/blob/master/Constraints/UrlValidator.php
symfony/validator's UrlValidator class pattern passes/validates an invalid url without a top level domain name extension, e.g. .com and doesn't throw exception

How to reproduce

$url = 'http://invalidurl'
$validator = new UrlValidator();
$validator->validate($url, new Url());

Additional context
I've come across this issue while using beberlei/assert which uses the pattern for url assertion, there's a direct link to the UrlValidator here on github from symfony, I've tried to check the pattern in both libraries and both seem to validate the invalid url as valid. See here - I consider the first example invalid, hope I'm not wrong.

Thanks for looking into this.
