Add --find-link flag to rye install

[Maxi91f]

We are using a local folder to store packages without a static html or pypi server for local development and CI.

On the pyproyect.toml we use something like this without any problem:

[[tool.rye.sources]]
name = "local"
url = "file:/some/path"
type = "find-links"

But on some scenarios we need to run something equivalent to install a package as global tool, but we couldn't find a way to configure rye install to use find-links. I imagine the command could look something like this:

rye install --path /some/path my_package --find-links

Trying to run the same command without --find-links doesn't works on our case, because on the folder we only have the .whl files.

I apology in advance if this was already proposed.
