resolve to oldest compatible uv version

[tpgillam]

setup-uv will look within e.g. pyroject.toml's tool.uv.required-version field to find any bound on the supported uv version. It will then resolve to find the most recent version of uv that satisfies these constraints.

We're currently wanting to resolve to the oldest version of uv that satisfies these bounds; basically like the '--resolution-strategy lowest` approach in uv itself. Might this be feasible?

The reason for this is that we'd like to add a test in CI to catch cases where our configuration requires features from a newer version of uv than we declare, e.g. if we require a newer managed python version than is supported with that version of uv.

Yes, this is possible to implement. No timeline yet though.
