Readthedocs: Don't let notebook failures pass silently

[EwoutH]

Adds both to docs/conf.py:

nb_execution_allow_errors = False
nb_execution_raise_on_error = True

To make sure that when one of the (tutorial) notebooks fails, the Readthedocs also fails and doesn't continue silently.

See the myst-nb docs.

Closes #2270.

Yeah apparently that's not a thing. Filed an upstream question:

[EwoutH]

The very friendly maintainers of myst-nb pointed me to these docs, which contained the answer.

When an error is introduced, the build now fails as expected:

@wang-boyu @adamamer20 I high recommend enabling this also for Mesa-geo and Mesa-frames.

that's very useful. I am using a markdown file for the tutorial currently but I need to turn it into a jupyter file. This option is supported into mkdocs-jupyter too
