Correctly rename uv existing lockfiles for use with --sync (#23522)

`uv` does a minimal update of existing lockfiles by default.
So implementing `generate-lockfiles --sync` in that case
is just a matter of making the existing lockfile available
in the sandbox.

Unfortunately in doing so we neglected to rename it
to the literal name `uv.lock` expected by `uv`, so 
the `--sync` functionality didn't generally work in this case.

This change renames the existing lockfile (if it is in fact
a uv lockfile). 

This mirrors the existing rename of `uv.lock` to the target
name in the repo.

This change also makes both renames use FileEntry
instead of FileContent, so we don't have to materialize
the lockfile contents into memory.
