Improve Readme and Contribution Guide

[c0nst4ntin]

With this PR I aimed to overhaul the old README to be a bit more clear and up to date.
In doing so, I also updated the license document to be up to date again.

Furthermore I moved some of the contents of the README.md to a new CONTRIBUTING.md and generally added some more information.

I also added a set of Issue Templates to give some structure to this project.

With all changes I looked at prismicio/prismic-client and put my own twist on things.

@angeloashmore @lihbr Hey, what do you think of this? Please let me know your Feedback. I would love to get this merged to give the package a newer and more welcoming look

Hi @c0nst4ntin, thank you so much for this!

I'll align with Angelo and we'll get back to you early next week at most about this. I don't think we'll have any objections against the updates, but maybe suggestions :)

[c0nst4ntin]

@lihbr Sounds great! Thank you. Maybe whilst you are talking to Angelo, could you also take a look at PR #204 & #207 and the discussion #205. We are all very unsure what the API Changes will mean for the PHP SDK

[lihbr]

Excellent work! I reported some suggestions from Angelo and I on the updated documents but nothing blocking if you prefer to merge it as-is.

Thank you so much for your ongoing effort maintaining the PHP kit over time 🙇‍♀️

Also, we just sent something your way over to your mail address :)

Thanks for the Feedback! It's really nice to hear your Feedback. I implemented most of your remarks and replied to everything. I will proceed to merge this now. If you notice anything else (or new), please just add a new comment and I'll be sure to fix it!

Also, we just sent something your way over to your mail address :)

Yes, I received the notification. Everything worked! Thank you so much, it was a really unexpected surprise!
I really appreciate you, Angelo and Prismic valuing my work!

@lihbr The Issue Templates don't seem to have taken effect yet. Do I need to configure them through the Repository Settings, or is this just a cache thing?

Let me know if I can help you or change anything?

Should be good now: be7a513, folder typo 😉
