DEPS: Adding missing doc dependencies to environment.yml

[datapythonista]

In #26648 we detected that environment.yml didn't contain some of the dependencies required to build the documentation. environment.yml is what we use to build the documentation locally. Adding them here.

I would put some comments and/or group dependencies in this file as much as possible

[datapythonista]

I agree, didn't think about additional grouping which makes sense, but was thinking on a comment for each dependency to explain where/why is needed. Otherwise will be difficult to know when any can be removed.

May be in a separate PR, since all them need it, and it's unrelated to the changes here? I'll create an issue, we have a sprint tonight where surely someone can work on it.

[jreback]

sure that's fine; I think grouping with a single comment is prob good enough

[datapythonista]

I opened #26659

[WillAyd]

Hmm this might cause some issues with xlrd throwing pending deprecation warnings as defusedxml seems to be getting installed as a dependency.

Seeing that locally at least let's see if it comes up in CI

[datapythonista]

The CI is not using this file. May be you can open a issue with what you see> I didn't see any new warning in the documentation build, didn't run the tests with this environment after the change.

[WillAyd]

For sure. I think it might be manifested in #22682 though if I see something more concrete will open an issue
