[dune] [ci] Fix and test release profile + use 1.1 dune-workspace

Dune 1.1 allows us to define the `env` flags in the workspace file,
which is a better place than the current situation.

Along the way, We fix the build flags for release mode [missing
`-rectypes` and add a `release` build profile CI job.
