I expected --resolution=lowest to imply --reinstall for an existing package

I ran:

uv pip install ruff # installs the latest version
> uv pip install --resolution=lowest ruff
Audited 1 package in 0ms

I expected that this would install the lowest version of ruff.
I think that either changing the behaviour, or documenting this is suitable.

I think our behavior here is actually okay, because it's consistent in general with how pip install works: if you have a satisfactory version in your environment, it defers to that. But we should document it somewhere / somehow.

We could also consider displaying a warning? That might be hard to do well though.

I think our behavior here is ok, though I can understand why it might be confusing on first run.
