I need this for debugging error messages.
I used an environment variable instead of a trace log so you can do
`UV_INTERNAL__SHOW_DERIVATION_TREE=1` and run a test to see the tree in
the test snapshot without further changes.
e.g.
```rust
// Resolving should fail.
uv_snapshot!(context.filters(), context.lock().arg("--preview").current_dir(&workspace), @r###"
success: false
exit_code: 1
----- stdout -----
UV_INTERNAL__SHOW_DERIVATION_TREE
root==0a0.dev0 depends on foo*
root==0a0.dev0 depends on bar[some-extra]*
foo==0.1.0 depends on anyio==4.1.0
bar[some-extra]==0.1.0 depends on anyio==4.2.0
no versions of bar[some-extra]<0.1.0 | >0.1.0
----- stderr -----
Using Python 3.12.[X] interpreter at: [PYTHON-3.12]
× No solution found when resolving dependencies:
╰─▶ Because only bar[some-extra]==0.1.0 is available and bar[some-extra] depends on anyio==4.2.0, we can conclude that all versions of bar[some-extra] depend on anyio==4.2.0.
And because foo depends on anyio==4.1.0, we can conclude that foo and all versions of bar[some-extra] are incompatible.
And because your workspace requires bar[some-extra] and foo, we can conclude that your workspace's requirements are unsatisfiable.
