DEPS: Update cython
- [x] xref #47978
- [x] xref #46848
Thanks @phofl 

we also want to add a release note (see 1.4.3, moreless copy and paste that one). Cython is a dev only dependency so I'll milestone as 1.4.4 for now.

we should probably also add the test from #47097 all the ci files and the setup.py also need updating Thinking some more (after https://github.com/pandas-dev/pandas/pull/47097#issuecomment-1202934142) I think ok to also add a release note for the regression fix too. Changed the other versions (forgot about them earlier) and added the test

lmk if there is a better place for this test Thanks @phofl . Let's give others chance to comment before we merge as I only opened the issue this morning. BTW, I've edited the description to not close the two issues, since we still need MacPython/pandas-wheels#188 as well. 您好，邮件已收到，谢谢！祝万事胜意！ Updated pyproject.toml too. Owee, I'm MrMeeseeks, Look at me.

There seem to be a conflict, please backport manually. Here are approximate instructions:

1. Checkout backport branch and update it.

```
git checkout 1.4.x
git pull
```

2. Cherry pick the first parent branch of the this PR on top of the older branch:
```
git cherry-pick -x -m1 8cb64ab539779e4efc3c8f002c14c852d45da3bb
```

3. You will likely have some merge/cherry-pick conflict here, fix them and commit:

```
git commit -am 'Backport PR #47979: DEPS: Update cython'
```

4. Push to a named branch:

```
git push YOURFORK 1.4.x:auto-backport-of-pr-47979-on-1.4.x
```

5. Create a PR against branch 1.4.x, I would have named this PR:

> "Backport PR #47979 on branch 1.4.x (DEPS: Update cython)"

And apply the correct labels and milestones.

Congratulations — you did some good work! Hopefully your backport PR will be tested by the continuous integration and merged soon!

Remember to remove the `Still Needs Manual Backport` label once the PR gets merged.
