treewide: remove FHSEnv
To remove the FHSenv, we have to patch rules_python to use
/usr/bin/env to resolve the path to bash instead of hardcoding it.
Additionally, we now bring a Nix-compatible Bazel 8.

+# Bazel 8 Nix Package
+
+This build is based on https://github.com/NixOS/nixpkgs/pull/400941, the only
+difference being the addition of `bash` to the default shell environment. As
+soon as the PR is merged, we can replace it with a small override to inject
+bash into the dependencies.
