make coq-htt package depend on coq-htt-core

[palmskog]

This approach could also be done with coq_makefile only, but much less conveniently (it would have to be like in the mathcomp repo with make -C htt/make -C examples).

@aleksnanevski could you please approve the CI run here? There may have to be some fiddling.

[palmskog]

OK, this actually looks like it works (so feel free to merge). Note that docker-action.yml and coq-htt.opam and examples/dune can't be generated via templates anymore for the time being, but maintaining those manually should be straightforward.

[aleksnanevski]

So you're saying I can erase the whole templates-extra directory? What about meta.yml and dune-project?
Also, shouldn't I change something in the coq-opam archive (e.g., erase the conflict declaration)?

[palmskog]

It's a good idea to keep meta.yml and use it to generated files like README.md and potentially dune-project as well. As for templates-extra, there doesn't look to be much point to keep the files there around.

There is no need to change any existing releases because of this - it will only affect (1) Git-based packages in extra-dev opam repo and (2) future releases. If you do a new release, e.g., 2.0.1, then I can depend on this much easier in Disel than 2.0.0.

[aleksnanevski]

Ok, I'll then make a new minor release 2.0.1, as you suggest.
