add 8.19.dev core-dev packages

ci-skip: coq-core.8.19.dev coq-stdlib.8.19.dev coqide-server.8.19.dev

@SkySkimmer do all 8.19 packages really depend on odoc, or is this just Dune-generated boilerplate?

[SkySkimmer]

They do, with-doc does build @doc which is odoc

(I think)
cc @ejgallego

[palmskog]

But the 8.18 packages also had build @doc, but no dependency on odoc. So I guess the question for @ejgallego is if something changed under the hood for 8.19 w.r.t. Dune+documentation.

[ejgallego]

I guess that was a bug in the 8.18 packages?

The doc target requires odoc.

[palmskog]

@ejgallego @SkySkimmer the coq package's build @runtest did not work properly without adding ounit2 as a dependency. Is this something I should report or fix upstream?

[ejgallego]

Is this something I should report or fix upstream?

@palmskog , I would have assumed that ounit2 would have been pulled transitively from the coq-core dep, but I'm unsure what the opam semantics are. What opam version did you test this with?

[palmskog]

@ejgallego it may be easiest if you take a look at one failing pipeline/job: https://gitlab.com/coq/opam/-/jobs/5707150494

All I know is that when I added the ounit2 dep, CI passed. It may have to do with transitive with-test deps not being installed.

[ejgallego]

Indeed, the problem is that the transitive deps are not installed. As of now we run the test-suite in the coq package, but at some point we could refine it and attach tests to particular packages.

I guess indeed opam expects the deps to be complete, so I suggest we add the missing dep to Coq's for now.

[SkySkimmer]

The ounit dep should be on coq not coq-core yes
