--find-links in requirements.txt not handled

[fviernau]

For example, the library torch==2.0.0+cpu is not on pypi.
It can however be installed by passing an URL pointing to an HTML page via --find-links to pip`.

This can be done inside a requirements.txt as follows:

-f https://download.pytorch.org/whl/cpu/torch_stable.html
torch==2.0.0+cpu

So, for above requirements.txt, python inspector is unable to "resolve" the dependencies.

I've meanwhile found that there is supported implemented for --extra-index-url[1].
This can be used as a work around in this case. At least if #143 is fixed, which I stumbled across.
