Do not use poetry2nix to build esctl.

Poetry2nix is not maintained anymore. We use a more native approach to build esctl. This requires to "downgrade" the requirements of some libraries.

Instead of downgrading dependencies (which I'm not a fan of, because dependabot will open dozens of PRs to bump them back up), I'd rather switch package managers.

A good contender is uv which I'm not a fan of either (only because it's backed by a for-profit company)

uv has gathered quite a large community of python developers though, and there is a maintained uv2nix project (mentioned in the readme of poetry2nix)

The other reason I'm not a fan of going to a more "native" nix approach here is that it forces 2 sources of truth for the package versions, the flake.nix and the pyproject.toml. People installing from nix and with pipx will also get different versions of the dependencies which is not a problem right now, but feels like it shouldn't happen.

If you want I can migrate the project to be built with uv instead to simplify the writing of the flake.nix file, would that be an acceptable compromise ?

As a temporary fix, while I migrate to yq, it's okay 👍
