[CI] Upgrade sphinx-gallery 0.11.1 -> 0.17.1

[clee2000]

The isolated subprocess build was preventing errors from surfacing, but upgrading to 0.17.1 (which has its own parallelization with joblib) makes it surface correctly

I only found 1 failure which was ax_multiobjective_nas_tutorial and it was because the ax-platform package got a new version that removed something it was using, so I pinned that too

We are also using split_code_and_text_blocks, which got moved somewhere else, so I changed that too, hopefully it is correct

Testing: on a different PR, I raised runtimeerror in one of the tutorials and saw that the error was surfaced
