System configuration

For bug reports, it really helps us to know:

• What OS are you running on? (Windows/MacOS/Linux)
• What version of scancode-toolkit was used to generate the scan file?
• What installation method was used to install/run scancode? (pip/source download/other)

[AyanSinhaMahapatra]

This is fixed now, see scan results after applying the commit above:

numpy-2.3.5.json.txt

Mostly what was needed is adding required phrases for the rules which were being matched as false-positives.
We need to really scale up marking required phrases for rules (and in complex rules with more than one licenses) as this will fix a lot of the false-positives by itself.
