Fix tezos compatibility with uri 4.0

[pirbo]

Uri 4.0 dropped (well separate into a new package) its dependency to re.

That revealed that, in 2 places in tezos, re is used without being explicitly declared in the dune files which now led build failure. These patches fix that.

Interesting, thanks for the fix. This sort of transitive dependency issue is difficult to spot in testing, but we've got ocurrent/ocaml-ci#257 open to see if we can simulate it better. Dune also supports implicit_transitive_deps and there are a few open PRs to improve the usability of this ocaml/dune#2733.

Note that tezos does not show up in the reverse dep list for uri at all: https://ci.ocaml.org/ocaml/opam-repository/pr/17411?history=7282de3706ca1661102d7ef80353bfe9db5a3822&test=2%20Revdeps

In general I would have asked to move the change to a patch release but the packages are all version-linked and that would require a full release. So in this case I am in favour of making an exception an merge the patch. @kit-ty-kate do you agree?
