DynamicPPL 0.36

[penelopeysm]

This PR adds compatibility with DynamicPPL 0.36.

Given that there are some reasonably breaking changes in the way that submodels behave, I've decided to increment the minor version number.

This PR supersedes the CompatHelper ones at #2532 #2533

Two problems right now:

(1) Prefixing broke Gibbs - this MWE works with DPPL 0.35.9 (main), fails with 0.36.0 (this PR)

using Turing

@model inner(m, s) = a ~ Normal(m, s)
@model function outer()
    s ~ InverseGamma(2, 3)
    m ~ Normal(0, 1)
    x ~ to_submodel(inner(m, s))
end
model = outer()
spl = Gibbs(@varname(s) => NUTS(), @varname(m) => NUTS())

sample(model, spl, 100)

I pushed a fix for this with aaa20c2e, but I think I need to understand GibbsContext more carefully to make sure that it is the correct fix.

Note that it's also quite likely that the change in DynamicPPL submodel prefixing behaviour means that it's now no longer possible to use Gibbs to sample prefixed submodel variables, because submodel variables now no longer have identity lenses. The current simplest workaround is for the user to not use prefixing. The proper solution is to fix #2403.

(2) There's some nasty lack of reproducibility in HMCDA sampling in test/mcmc/Inference. It's not introduced by this PR because the last CI run on main was already failing. I can't yet repro this locally.
