Update .gitignore - adds py environment folder

All the files and folders in the py environment folder are appearing as new changes to commit. This repository doesn't include that folder, so I added the py folder to ignore it.

This command creates the py environment folder:
./scripts/build_python.sh -i py

Explanation is here:

connectedhomeip/docs/testing/python.md

Lines 517 to 523 in bf4edc4

	Next build the python wheels and create / activate a venv (called `py` here, but
	any name may be used)
	```
	./scripts/build_python.sh -i py
	source py/bin/activate
	```

What is a py environment folder? What build process creates that?

I do not have such a thing.

What is a py environment folder? What build process creates that?

I do not have such a thing.

Specifcally:

• name does not feel special (no __ prefix nor . even for hidden)
• name is actually common, like scripts/tests/py/ and src/test_driver/efr32/py/

We have to figure out what build command creates it and dirties the source tree. Please add this information to the PR summary so we can determine if the command is buggy or if we really need to ignore (and add details to gitignore).

Just ignoring things that dirty our source tree is not ok (we should not accept dirtying of the source tree)

I can update it to this
/py
This will only target the py folder in the root folder, not subfolders

Shouldn't builds go into out or something like that which already gets gitignored?

We should fix the documentation to place it in out/py.
