Get possible values based on regex input

### What's the Problem?

I need to get values matching a regex. They can be very complicated, and I would like to get some test values to run against a regex.

### Solution/Idea

If I have a regex like this `^[a-zA-Z0-9]+(-*[a-zA-Z0-9])*$` I would like to get a list of values that match this (or just one value matching it)

### Alternatives

I tried various tools like https://onlinestringtools.com/generate-string-from-regex and for at least the regex above they give me some gibberish...

### Comments

Nothing I can think of...

No files, tests, or entry points are mentioned. Start by locating the regex-related tool or feature in the DevToys codebase, then review how inputs and generated values are handled. Done means generating at least one readable value that matches the supplied regex, including the example pattern.
