[Enhancement] Versionning documentation

[leleogere]

this docs is a bit too "up-to-date" as it concerns the incoming MidiTok V3 but the concerned paragraph is still 100% relevant

As you mentioned in this comment, the current documentation might not match the version of Miditok that people are using. It would be very useful to be able to use the bottom-left button of the website to see the documentation of a particular version. Currently, we can see that all versions are referenced, but only the last one is documented. Clicking on any of the previous versions ends up on a 404 error.

I do not get 404 errors when I try older versions.
Are you accessing to a particular page that might not exist on older versions?

https://miditok.readthedocs.io/en/v2.1.8/

Woops, that's my bad, I was on a page that didn't exist previously indeed... Problem solved I guess! 😅

The issue was that I was on the "Bases" page (first item on the left menu, as showed in my screenshots), which I expected to be in most versions. I appear that it exists both in 3.0.0 and 2.1.8 (and earlier), but that do not share the same URL. In 3.0.0, the "Bases" is located at ..../bases.html, and in 2.1.8 (and earlier) it is located at ..../midi_tokenizer.html. So when you switch versions on this page, you get a 404 error.

Indeed the doc file has been renamed to match the page title 😄
