Fix docker push CI

[cmdoret]

the docker build and push CI workflow fails with:

#24 2.746 OSError: libgomp.so.1: cannot open shared object file: No such file or directory

Objective: Fix CI

Requirements:

• Investigate issue in logs
• Update Dockerfile as required
• Trigger image push

Source of the issue from here. For the last point, I can't trigger the push myself.

Looks like there's an OS incompatibility issue:

Unable to find installation candidates for typecode-libmagic (5.39.210531)

Next steps:

• Check alternative options to keep arm64 architecture
• If yes to point above: consider if it's worth the effort
• If no, discuss dropping the architecture or the dependency

Insights so far:

• scancode-toolkit ships with typecode-libmagic, a binary python package with an optimized libmagic. It is fast, but not arm64-compatible
• scancode-toolkit-mini does not ship typecode-libmagic and can use the system's libmagic. It works on any platform, but is very slow

EDIT: both versions might actually be equally slow

[supermaxiste]

Shall we can keep the toolkit as is and fix the docker push for this issue?
For optimizing the scancode-toolkit we can open a separate issue, what do you think?

[cmdoret]

Agreed, optimizing would likely be replacing: for which there is now this issue: #89
