Subject: [PATCH] docs(forms): Custom Validator example selector name
 incorrect. (#20464)

Name of selector in ForbiddenName example is not consistent with Validator class nor Html selector example. Added the selector name 'appForbiddenName' as an alias name for the input of the Validator class, and updated the view accordingly.

Fixes: #20206

PR Close #20464
