[WIP] Adapt docs to latest SciML releases

[TorkelE]

WIP, mostly uploading so that I can work on PR from multiple computers.

[ChrisRackauckas]

This is missing the attractors floor?

[TorkelE]

Yeah, there is a few things missing, but I will add that when I update things for when the new OrdinaryDiffEq.jl is available as I need that anyway.

[ChrisRackauckas]

It should be available now.

[TorkelE]

excellent, will have a go at it thsi afternoon

[TorkelE]

Awaiting SciML/OrdinaryDiffEq.jl#3771, but after that this should hopefully be quick work

[ChrisRackauckas]

I wouldn't worry about the QA here, https://github.com/SciML/Catalyst.jl/actions/runs/28762798445/job/85281268352?pr=1488 , that will shortly get replaced the moment you finish this #1487 with a more updated QA setup. The segfault is probably the JET thing that this works around. So, I think this is good sans the modeling LTS failure. That's probably from writing the catalyst equivalence in a way that isn't robust to changing symbolic hashes, i.e. the ordering of the variables x + y vs y + x kind of thing.

[TorkelE]

Sounds good, will have a look at that failure and merge later today I hope.
