Release 0.2.0

[veronikakurth]

Remark: given the semantics of the changes (no features!), this should have been a minor release. The reason behind it being a major one is a significant divergence between the old release branch (qutip-qoc-0.1.X ~ 2 years old by now) and the current main. Upon attempting to merge a new minor-release-branch (say, fork/qutip-qoc-0.1.2, which based on current main - doing so because we need all the changes from main in a new release) into the old qutip-qoc-0.1.X, not only merge conflicts appear (which are possible to solve) but also bugs in the RL module. Upon our investigation (with @BoxiLi) the latter happens due to inconsistencies between commit history in qutip-qoc-0.1.X and main caused by cherry picking in qutip-qoc-0.1.X.

Thus, the cleanest and easiest way for us to proceed is via creating a new branch based on main and making it a major release.
Once the release happens more regularly, it will be easier to keep to our regular release procedures.

@BoxiLi Added release notes to this PR - we can use them later after doing release via GitHub Actions. :)

@BoxiLi Is it possible to rename the milestone with which we tracked PRs from 0.1.1 to 0.2.0? To avoid confusion.

I think #48 is not included here. No big deal since it is just doc requirements. Just for the note to be accurate

[BoxiLi]

I probably merged it after creating the branch. So the label was misleading.

It is there, the section with dependency upgrades looks a bit cluttered, I will improve it!

And in general I agree we should not miss anything. Ideally, we should also automatize workflows with change logs like in qutip. :)
