Clarify what you can do with the .subscribe Disposable

[tmewett]

Not certain this is right, please correct :)

Disposable nor DisposableBase are not documented so it wasn't clear what you could do with them.

Thanks, yes it good to precise it here. Especially because many small examples do not show the disposal.

@dbrattli I do not understand why the code-quality check fails while they succeed on master.

There appears to be an issue with isort/poetry which caused issues on multiple repos that depend on this pre-commit; it is fixed in 5.12 and in 5.11.5 (for python 3.7 compatibility)

https://github.com/PyCQA/isort/releases/tag/5.11.5

On #689 I attempted to bump isort to that version but my Poetry appears to be a more recent version and made a lot of changes so had to revert.

Can this be merged?
