html5pattern.com no longer exists but leads to a suspicious site

[szabeszg]

A ProcessWire Text Field can optionally have a Pattern, defined on its Input tab when editing the field in the admin.

Currently the option has the "Notes":

See html5pattern.com for examples of patterns you can use and create.

However, html5pattern.com no longer exists and the link leads to a suspicious site.

I did not find an alternative site to recommend, but maybe recommending both MDN and Regexlib is a good alternative:
https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Attributes/pattern
and
https://regexlib.com/

The new notes could be:

See MDN for HTML pattern attribute details and browse regex examples at RegexLib.

@szabeszg, this is already fixed in processwire/processwire@421a88c, but I'll leave it open if Ryan decides to add a RegexLib link.
