We need the new dates_calc and sedlex
Debug notes:
We need the latest ocamlpro/ocaml image (2024-05-26) to get the release of
dates_calc. Unfortunately, it breaks: `pip install gmpy2` could not find
pre-built binaries, so it would "transparently" try to recompile and then
complain about obscure system packages missing (mp libraries). Indeed the newest
image picked up the newer Alpine release (3.20), which is based on a newer musl
release (and apparently that's a problem !?).
Hopefully the proper python dependencies will become available at some point ?
Always generate the version through git when possible, and encode that within
the binaries so that `catala --version` does'nt give misleading information.
Previously we used dune's builtin functionality, but that resorts to a hack at
install time which is unpleasant and doesn't work with our use of `opam
install`.
The cost is a re-linking of catala_utils and the binaries upon git commit, which
is hardly noticeable.
* Use the newer "pyproject.toml" for syntax highlighters
* Use venv for everything (previously, the pygment lexers were installed
globally, but more recent Python releases frown upon that. This will probably
be more stable in the long run...)
* Use one venv at the root of the project (`_python_venv/`) for both
pygments and the runtime
* Initialise this venv automatically from the Makefile (it should no longer be
necessary to run scattered `set_up.sh` scripts with mysterious interactions)
On the downsides, though:
* Only tested with Python 3.11 at the moment
* Need to remember to activate the venv (`. _python_venv/bin/activate`) from the
root for e.g. HTML literate output to work. A more manageable solution could
be for Catala to provide the lexers on-the-fly when calling `pygmentize`.

Gasp, I only now noticed this; it should absolutely be avoided, in general (the
Docker image is expected to contain a recent repo), and in particular after
switch creation.
Switch to a newer image instead (or just remove the date constraint in FROM but
stable builds are good).
- fix dune compilation options: ensure both no dev failure on warnings and CI
failure on warnings (the defaults do neither of those things !)
- attempt to publish the build artifacts to github-pages, so that they could be
made more easily available and we could maybe remove the ones that are still
there from the main repo
