Describe the issue linked to the documentation

Single ticks render as italics while double ticks render as code in the api docs, e.g. int v.s. int. Various methods use this inconsistently, example from the HIVECOTE 2.0 docs below:

Docstring for random_state uses single ticks (italics) for all references to code, i.e. int, RandomState, and None.

Docstring for n_jobs uses double ticks for -1 to represent it referring to code.

Suggest a potential alternative/fix

Select preferred approach out of single and double ticks for referring to code in docstrings and apply consistently throughout aeon.
