Add support for Maps on request_body matcher

[scudelletti]

Hello there! 👋
First of all thanks for maintaining this library! It's awesome and I use it a lot!

I've noticed that after upgrading to Elixir 1.15 - OTP 26 some tests started failing due to the order of keys/values changing when encoding the JSON body.

I know I can write a custom matcher or try to write a regexp but I believe this may be useful to more people too.
Would such feature be of interest?

This PR implementation is not ideal so please let me know what implementation would you prefer in case you like the feature. I also thought about adding a new option like :request_on_json_body. I'm open to suggestions.

Thanks for the PR, and I'm very sorry being late to respond 🙇 . I believe #211 is addressing the same issue, I am wondering 211 might be simpler implementation. Do you think merging 211 resolve the issue you're facing (or this one is better?). I appreciate your feedback 🙇 .

Hi @parroty, thank you for the reply, you are very kind.

I agree, #211 seems better suited and solves the same issue.
I'll close this PR.

I wish you a lovely day! 🙇
