Use of Protocol requires Python 3.7 or newer error from typing_extensions

Environment data

• Language Server version: 2022.2.0
• OS and version: any x64
• Python version (and distribution if applicable, e.g. Anaconda): 3.6
• python.analysis.indexing: null
• python.analysis.typeCheckingMode: off

Expected behaviour

from typing_extensions import Protocol

class Foo(Protocol):
    ...

This would have no errors. This worked in Pylance version 2022.1.5 (released 1 wk ago)

Actual behaviour

Error: "Use of Protocol requires Python 3.7 or newer"

This seems to have broken in Pylance version 2022.2.0 (released 3 days ago). I would expect to get this error if I import from typing, but typing_extensions implements this for older versions of Python and Pylance was able to distinguish these until this latest release.

This was a regression introduced by a recent change in the typeshed stubs. A fix will be included in this week's pylance. For details refer to this issue in the pyright repo.
