[New-bugs-announce] [issue46386] Improve `test_typing::test_immutability_by_copy_and_pickle`

[Nikita Sobolev]

New submission from Nikita Sobolev <mail at sobolevn.me>:

There are several problems with this test: https://github.com/python/cpython/blob/d02c5e9b55a8651b7d396ac3f2bdedf1fc1780b5/Lib/test/test_typing.py#L2130
1. It does not test all `pickle` protocols
2. It does not test newly added `ParamSpec` (probably others, I will double check)
3. It does not clean up `global TP, TPB, TPV`

I will send a PR for this :)
