CLN: Remove MultiIndex._get_grouper_for_level

[rhshadrach]

#49373 removed its only use. Since it's implemented on Index as well (where it's still needed), I think we should raise NotImplementedError to prevent any hard-to-understand tracebacks.

@Himanshuwagh - I'd be happy to - is there a part that is unclear?

@natmokval - It looks like @TaylorChaseHunter is already preparing a PR for this issue.

[TaylorChaseHunter]

Oh I'm sorry, I was just kind of practicing the process -- I didn't realize it notified here. @natmokval please feel free to take it and I'll remove my commit.

[rhshadrach]

Ah - no problem @TaylorChaseHunter. Thanks for letting us know!

[natmokval]

Oops, my mistake. I am quite new to the process too. @TaylorChaseHunter please take the issue and don’t remove your commit.

@rhshadrach I made changes off the main branch but tests failed. Pretty sure your changes in #49373 are necessary? If so, should I branch off your branch or wait for that to merge then cleanup? Thanks!

edit: clearly depends on #49373. I'll wait for that merge then PR

[rhshadrach]

Exactly right @codamuse - that PR should be merged in the next few days, thanks for waiting.

[rhshadrach]

@codamuse - #49373 has been merged.

[codamuse]

@codamuse - #49373 has been merged.

Thanks for the heads up, I'll PR the change tomorrow.

Hi! I am a first time contributor and would love to help. Is there anything that I could possibly be assigned to or help out with?

@rhshadrach Sorry but I've been trying to get tests to pass locally and not having much success. I cloned a fresh repo from pandas-dev:main, setup my docker environment, cythonized, then ran tests from the panda-dev environment in conda and I get lots of fails even when trying different options with pytest. Could be something with my setup, I dug into a little bit but couldn't figure it out. I've decided to setup a draft PR in my fork for the change and see how the checks go there in case there's something strange happening in my environment. I'll keep checking locally, none of the tests are at all related to the change I made (removing that function in multi.py). I'll keep you posted.

encouragingly the CI tests all passed...I'll try to sort out my local environment but I think this PR should be okay
