ci(check-mapping): expanded license checker with more general use case

[Biscgit]

License checker rework

Reworked the original license checker that has been added with #3699 and also includes proposed changes in #3731.

Fixing #3714:

Added a new file record_mapping.yaml that acts as a schema to validate records against. In the file, it is possible to define this using yaml/json.

Some specialties:

• In case of the record value being a list, the sub-pattern gets applied to all elements of that list
• Adding a ? to the beginning of a field in the schema makes its presence in the record optional
• Values are checked against finally defined lists of strings (case-sensitive) or a single string
• Leaving the value of a field in the mapping empty will only check if the field exists.

The following example would ensure, that the field description is present and of any value, only when abstract is also present. If abstract is not present, it will not check for description:

?abstract:
  description:

Fixing #3715:

By passing arguments in the cli, it is possible to add multiple paths to folders or files to check against. This supports unix-like syntax, (i.e., wildcards, etc.) and multiple paths separated by space.
Furthermore, added a check on top of the default for only changed records, if any.

Fixing #3716:

Limited output of the checker. By passing -v all checked paths will be printed. Instead of printing the errors on failing, a summary card will be printed. Furthermore, this now catches different errors that occur in the same record instead of stopping after finding one.
