Functions in os module only show type stubs information (both on hover and when doing "go to definition")

Issue Type: Bug

Hello,

Seems related to https://github.com/microsoft/pylance-release/issues/2304 but that issue says to open new issues for similar problems, so here goes.

Hovering a function in os shows only type stubs, no docstring:

And going to definition (ctrl+click) brings to the stubs rather than implementation (which I guess is normal since it's probably compiled code? but I'd still like to be able to see the docs...)

Me too. How should I fix it

[ldorigo]

@bschnurr does the "needs investigation" label mean some information is missing? I'm happy to provide more info/run tests if necessary

[debonte]

@ldorigo "needs investigation" means that the Pylance team needs to spend some time investigating this to determine what action to take.

[bschnurr]

I see on windows 'os.chmod('/tmp/foo', 0o777)' has no docstrings either

[bschnurr]

turns out that os.py is using some dynamic behaviour to remap functions that breaks our docstring logic. Some new way of mapping these docstrings is needed.
