StrEnum not recognized as a string by dictionary update

[acampove]

Describe the bug
When using update, to update a dictionary, the keys of the dictionary are StrEnum, but pyright complains because it expects a str

Code or Screenshots

from enum import StrEnum

class Region(StrEnum):
    NORTH = "north"
    SOUTH = "south"
    EAST = "east"
    WEST = "west"

d1 = {Region.NORTH : 3}
d2 = {'one': 1, 'two' : 2}

d2.update(d1)

That shows me:

WARNING: there is a new pyright version available (v1.1.407 -> v1.1.408).
Please install the new version or set PYRIGHT_PYTHON_FORCE_VERSION to `latest`
