Add `COSMIC` as a desktop option

Written in Rust, looks pretty promising.

COSMIS is pre-alpha. Once a stable (or anything but alpha) release is made, it'll get packaged pretty fast and we can add it as an option. For now, it's a non-starter, cause that's probably several years away.

Thank you @killertofus for the PR, I requested some minor changes - after which I can merge and it will be joining the next release :)

I made the mistake of not checking the fine print on the COSMIC GitHub which states:

incomplete alpha

I will push a patch to hide this DE behind --advanced so that we don't cause unintended bug reports during next months ISO build. And I'll put a monitoring on their GitHub for a stable release and remove the advanced flag once it's out.

They released alpha 2 yesterday. Still not out of the woods yet :)

Not sure if they consider it stable, or the README is just lagging behind:

Currently in beta for Epoch 1 (the first release), which is nearly feature-complete and in the final bug fixing stage.

If this is True, we might be better off waiting still?

I believe that readme isnt updated yet.
It mentions 24.04 LTS beta whilst 24.04 stable release was yesterday along with version 1.0.
