Documentation is unclear to available validator methods

[sisp]

All built-in Jinja2 functions/filters/tests, filters from jinja2-ansible-filters (which includes regex_search), and the function pathjoin are available. Additional Jinja2 extensions can be registered via the _jinja_extensions setting in copier.yml. regex_search is no validation method but simply a Jinja2 filter. Using grep output isn't supported out of the box, it may be added via a custom Jinja2 extension, but I'm not sure it's a good idea because grep may not be available on all systems and – depending on what exactly you're planning to do – validation may become non-deterministic.

Thanks for your feedback! Would you like to open a PR to improve the docs?

I don't want to replicate docs from jinja2-ansible-filters, but a info box could help indeed.
