feat: Removing detect_missing_libraries arg

[MBerguer]

What 💻

There are a couple of reasons for removing the arg:

1. This has not worked as expected since we started working on the Solc linking because of (2).
2. The missing libraries are always reported in another format on the output, and you can see them using --json (if any)
3. This arg will be removed entirely in the following weeks when we move to version 1.5.8; see this for more info
