CI: fix wrong syntax in CI env yml files (mamba 2.0 compat)
All CI is failing with the new mamba 2.0 release. But it seems this is because we had invalid syntax (pip extras syntax) in our environment files, where mamba now fails on (previously used conda for parsing the yml files).

It seems like there a few issues with mamba 2.0 with windows (https://github.com/mamba-org/setup-micromamba/issues/227) and the `list` command (https://github.com/mamba-org/setup-micromamba/issues/225) that we're also seeing here.

We may just need to pin the mamba version I opened #59912 - planning to merge as soon as that's green. We can then use this to unpin once upstream is fixed. This pull request is stale because it has been open for thirty days with no activity. Please [update](https://pandas.pydata.org/pandas-docs/stable/development/contributing.html#updating-your-pull-request) and respond to this comment if you're still interested in working on this. Thanks @jorisvandenbossche  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 2.3.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 de4eaf8b2e7c6b840dbd0198d8c3edf5eaf5afff
```

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

```
git commit -am 'Backport PR #59910: CI: fix wrong syntax in CI env yml files (mamba 2.0 compat)'
```

4. Push to a named branch:

```
git push YOURFORK 2.3.x:auto-backport-of-pr-59910-on-2.3.x
```

5. Create a PR against branch 2.3.x, I would have named this PR:

> "Backport PR #59910 on branch 2.3.x (CI: fix wrong syntax in CI env yml files (mamba 2.0 compat))"

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.
