Documentation request: more examples of rules

[Lenormju]

I find that the README is too minimal, It gets you started, but to find more examples you have to search each of the tests. Would you like to consider adding examples on the Readme page, either some impressive ones, or link to the github files directly (like https://github.com/zyskarch/pytestarch/blob/main/tests/test_architecture.py for example).

Also, why not a full snippet, including the pytest parametrize like you do in the pytestarch tests themselves ?
