Bug#1040874: ocaml-dune: Please add ocaml:Provides to d/control

[Dan Bungert <daniel.bungert@canonical.com>]

Source: ocaml-dune
Version: 3.9.0-2
Severity: normal
X-Debbugs-Cc: daniel.bungert@canonical.com

Dear Maintainer,

utop shows the following in testing migration:
* libutop-ocaml-dev/amd64 has unsatisfiable dependency

Attempting an install of libutop-ocaml-dev reports:
 libutop-ocaml-dev : Depends: libdune-ocaml-dev-v9190 but it is not installable

I believe that adding the ocaml:Provides will resolve this. Debdiff attached.
