ci: key Rust cache on resolved Python version (#1554)

* ci: key Rust cache on resolved Python version

The Swatinem/rust-cache key didn't include Python's patch version, so when
the runner image bumped Python (e.g. 3.14.4 -> 3.14.5) the restored build
artifacts kept absolute LIBPATH entries pointing at the prior install dir
and the link step failed with LNK1181 looking for python3.lib in the old
3.14.4 path. Reorder setup-python before rust-cache so its output is
available, and append the full python-version to the cache key.

* ci: use env.pythonLocation as Rust cache key

Replace the steps-output approach with the env var setup-python sets
automatically, removing the need to assign each step an id.
