chore: add example for a simple regex match on an input

[lukeocodes]

I hope you don't mind. I thought examples/ could do with a few more basic prompts in there. This is the first of a few I was thinking of. I will PR the others when I get time.

Any reason to return a Promise in the example since the effective check is synchronous?

It seemed to suggest it preferred a promise as a response! I will change it

[SBoudrias]

Yes and no, maybe examples are often async to be more easily extendable. Not against keeping the promise there, I was just wondering the rationale.

Can you help fixing the linting errors?

[lukeocodes]

I think it is easier to understand without the promise so I've switched it.

[lukeocodes]

Can you approve the workflow and i'll resolve the linting from the latest version. Thanks!
