Escape underscores and other special sphinx characters

see e.g. https://github.com/OpenMS/OpenMS/commit/4e41abd4a49052549aa9f4547fb8ed1bd534b14d

Where in_ would lead to invalid target errors. This needs to be done in all "*.pyx" files in the OpenMS/OpenMS repository. Not sure if there are more cases but someone needs to check.

Hey @jpfeuffer, I need more context for the issue. Can you please elaborate or we can discuss this in the weekly meet?

Basically make sure everything is rendered properly, even if there are special characters in the variable name.

Might be fixed by the linked PR. We need to check if this is fixed in the logs.
