Add missing analysis dependency to experimental reals dev package

[JasonGross]

The development version of coq-mathcomp-experimental-reals now imports mathcomp.esum, mathcomp.ereal, and mathcomp.numfun. Those modules live in the coq-mathcomp-analysis package, but the opam metadata did not declare that dependency, allowing the experimental-reals build to start before analysis was available.

Add the matching-version analysis dependency so opam orders these builds correctly.

Validation: opam lint passes for the updated package. The observed build failure was Unable to locate library esum with prefix mathcomp; the analysis development package was concurrently still building, confirming the missing dependency edge. Full source validation will follow once that long-running dependency build completes.

CI note. Rebased onto master. The opam-build:4.09.0 failure this PR was showing was rocq-runtime.9.3.dev dying at ./configure with "You need OCaml 4.14.0 or later"; that is fixed in master by #3803, so the rebase clears it. An earlier revision of this branch also carried a dune < 3.24 bound for rocq-elpi.dev and rocq-micromega-plugin.dev; that has been split out into #3806 so this PR is the one-line dependency fix only.

Update (rebased again). #3806 has merged, so the elpi/micromega dune < 3.24 bound is now in master. This branch is rebased on top of it; the opam-build:4.14.2 and 5.3.0 failures were mathcomp-analysis pulling in rocq-elpi.dev, so they should clear too.
