We had several cases where interpreter discovery fails. This PR improves
the verbose output to ensure interpreter discovery is debuggable for a
user.
In the process, i removed the custom gourgeist logic for the
uv_interpreter logic.

Gourgeist
Gourgeist is a rust library to create python virtual environments. It also has a CLI.
It currently supports only unix (linux/mac), windows support is missing.
Rust
use camino::Utf8PathBuf;
use gourgeist::{create_venv, get_interpreter_info, parse_python_cli};
let location = cli.path.unwrap_or(Utf8PathBuf::from(".venv"));
let python = parse_python_cli(cli.python)?;
let data = get_interpreter_info(&python)?;
create_venv(&location, &python, &data, cli.bare)?;
CLI
Use python as base for a virtualenv .venv:
gourgeist
Or use custom defaults:
gourgeist -p 3.11 my_env
Jessie's gourgeist
