Incompatible with typing-extensions 4.6

Got this error when upgrading typing-extensions to 4.6. pydash works fine with typing-extensions 4.5.

I did some bisecting of the changes between typing-extensions 4.5.0 and 4.6.0 and found the changes in https://github.com/python/typing_extensions/pull/137 to be the culprit.

I have posted on that PR for any pointers on how to fix this incompatibility, as I can't immediately work it out.

typing-extensions 4.6.1 has been released now which fixes this.

With the typing-extensions package’s fix, shouldn’t pydash also change its own requirements to avoid importing the culprit version — this requirement

install_requires =
    typing-extensions>=3.10

seems rather loose to me.
