drop jQuery dependency

[BoPeng]

bootstrap5 beta is out and the biggest change would be the drop of jquery dependency.

I just briefly tested bootstrap-toc on my website and it appears to be working properly as long as I load bootstrap5 and jquery. I am not quite sure if it is worthwhile to stop using jquery in bootstrap-toc but it would be nice if someone tries to tackle it.

Ah, good to know. https://github.com/afeld/bootstrap-toc/issues/16 would probably be a good way to future-proof against that problem.

Would love some help on that if interested!

Had a look at #16. My "working properly" might be wrong since scrollspy might not be working properly. Anyway, I think dropping dependency on jquery is more important than dropping dependency on bootstrap.

Got it. Re-titled to reflect that. Seems very doable, though not sure when I will get to it. Pull request welcome!

Hey,

I started working on this feature, I was almost done when I noticed that I made a mistake. The $scope option can contain more than one element in this library, but my implementation assumes that it's a single element.

I'm pretty tired now to fix it (and I don't know if/when I'll want to continue it), but I'll link my fork so you can maybe take it and improve it, and hopefully finish this transition.

I'm available if you have any questions.

PS: Commits are pretty messy, but I left them separated to better show the steps I took.
