Rewrite setup (#2865)

* Updated testing requirements based off extra["testing"]

* Updated setup to check the version is valid, added testing and all dependency groups and collects the requirements from requirements.txt to keep everything standardized.

* Updated requirements.txt based on the current minimum gym requirements.txt to work

* Updated requirements.txt based on the current minimum gym requirements.txt to work

* Updated test_requirements.txt based on the current gym full testing requirements

* Pre-commit updates

* Add integer check for the `n` parameter

* The type of self.spaces is an Iterable which is absorbed by the tuple.

* Simplifies the environment checker to two files, env_checker.py and passive_env_checker.py with a new wrapper env_checker.py

* Adds the passive environment checker on `gym.make`

* Ignore the `check_env` warn parameter

* Ignore the `check_env` warn parameter

* Use the `data_equivalence` function

* Remove env_checker PR changes

* Move pip install pytest and mock to py 3.6

* Update setup.py and requirements.txt
