Add a section on checking is regex

[Josh-Cena]

Summary

Motivation

I intended to document that endsWith() etc. would throw if the parameter is a regex. In doing so I figured that we document in multiple places how the IsRegExp check works. It makes sense to have a dedicated section, similar to #20234.
