Dream 1.0.0~alpha8: tidy Web framework

[aantron]

The main prompt for this release is that Dream formerly vendored ocaml-h2 and hpack, and the vendored version of hpack was not compatible with OCaml 5.3. This release removes the vendored http/af stack in favor of httpun from opam, which is the renamed and released version of the stack (aantron/dream#357).

Looks fine -- there's is lower bounds failure on gluten-unix though it might be unrelated

[lower-bounds (failed: gluten-lwt-unix.0.5.0 failed to build)](https://opam.ci.ocaml.org/github/ocaml/opam-repository/commit/0750dded834f010d1114fd48fff22182cbbd2b15/variant/compilers,5.1,dream.1.0.0~alpha8,lower-bounds)
