Drop the `Pkg.develop` of OrdinaryDiffEq and StochasticDiffEq in the docs build
(and the env-setup re-clone dance), resolving them — and all the solver
subpackages — from the registry at their released versions instead of master.
Why:
- StochasticDiffEq is a subpackage of the OrdinaryDiffEq.jl monorepo as of v7
(registry `repo = OrdinaryDiffEq.jl`, `subdir = lib/StochasticDiffEq`), so
`Pkg.develop("StochasticDiffEq")` re-cloned the same monorepo and the stale
leftover checkout of the old `SciML/StochasticDiffEq.jl` repo (6.100.0) broke
resolution against the docs `[compat] = "7"`:
ERROR: empty intersection between StochasticDiffEq@6.100.0 and compat 7
- `Pkg.develop`ing the monorepo master also risks version skew: the dev'd
master meta-package's subpackage [compat] must be satisfiable by the
*registered* subpackages (sources don't propagate to the docs project), which
breaks whenever master races ahead of the registry.
- The released packages already ship their `docs/` (OrdinaryDiffEq 7.0.0's
tarball includes `docs/` with pages.jl + src + common_*_steps.jl), so the API
docs can be copied from the installed stable packages with no dev checkout.
Net effect: the stable docs reflect released versions, the stale-checkout failure
mode and the monorepo skew are both gone, and env-setup is just instantiate.
(StochasticDiffEq's registered tarball does not yet ship `docs/` — its docs/ needs
to be migrated into lib/StochasticDiffEq in the monorepo; until then the
"StochasticDiffEq.jl API" section stays dropped, as added in SciML#869.)

Building against the stable release (previous commit) surfaced that OrdinaryDiffEq 7.0.0 does not re-export `EnsembleProblem` (master does), so the low-dependency example's `ODE.EnsembleProblem` was an `UndefVarError`. Source it from SciMLBase, which defines it — consistent with this page's own point that "you will always need SciMLBase.jl, since it defines all of the fundamental types." This is the only docs `@example` affected: across all of docs/src the only OrdinaryDiffEq-exported-on-master-but-not-7.0.0 symbol used via the alias is `EnsembleProblem`, here. Verified locally on the released stack (OrdinaryDiffEq 7.0.0 + OrdinaryDiffEqLowOrderRK + DiffEqCallbacks + SciMLBase): the example's ensemble solve runs successfully.

#870 fixed the Documentation build failing on a stale

After this,
make.jl's ownPkg.developcalls for the two are no-ops on the freshly-cloned checkouts.This is a prerequisite for #871 (the AMG default-coarse-solver docs cleanup), whose Documentation build currently fails here before reaching any
