sphinx allows to develop your own directives,
in order to check correctness, we want to have support in the linter instead if ignoring all of the custom directives

As of now, there is unfortunately no way to register your own roles or directives.

I think this would require a much more sophisticated configuration system, where an INI file is not sufficient and would need to be replaced by a python source file which gets loaded (like sphinx does). But unlike sphinx rstcheck has a config hierarchy system within the config auto-detect functionality, which may or may not make problems with python source files for configuration.

If you have a good idea, I am open for discussion and PRs.
