Get rid of lowest-direct resolution in no-constraint upgrades with uv (…

…#38109)

When we fall-back to no-constraint mode in uv, we used so far
lowest-direct resolution - but it could cause a really old set of
versions to be installed with some strange pyproject.toml errors
(for example zenpy==2.0.32 had a buggy pyproject.toml and it
caused editable local install to fail.
