DOC: tab sync based on same tab name using sync statement

[RobPasMue]

Reference issue

None related.

What does this implement/fix?

When selecting an OS tab in the documentation you can also use :sync: to easily sync all tabs related (i.e. with the same name). See the video attached.

Thank you @RobPasMue! That's a good addition 😃

Could you also sync venv/conda on this page?

For the next commit, could you please add in its message the following to skip some of the CI: [skip actions] [skip cirrus]. We only need to build the doc for doc only PRs.

Seems like a good idea to me, thanks @RobPasMue

This implies adding the dependency

This works as-is with sphinx-design (see https://sphinx-design.readthedocs.io/en/latest/tabs.html) which is already a dependency, so no need to add a new dependency.

Thanks @rgommers - indeed, I tried it first with sphinx-tabs. @melissawm here at SciPy Conference mentioned to me that the dependency had been dropped some time ago in favor of sphinx-design. That's when I started investigating how to do it with sphinx-design. I just edited the PR description 😄

Sure, you can count on it @tupui! Working on it right away =)
