Why:

Closes: #32305

What's being changed (if available, include any code snippets, screenshots, or gifs):

As agreed upon in the linked issue, additional hashFiles examples were added, showcasing more advanced pattern matching options. In keeping with the tech referenced in the article's current examples (JavaScript/Ruby), the following file extensions were used: .js and .rb. The single-pattern examples provide use-cases for patterns involving fixed-level directory search and recursive subdirectory search. The multi-pattern example makes use of a fixed-level exclude ! pattern in a recursive subdirectory search.
