Generate rules automatically using github search API

There are a lot of new licenses added and it is nice if we have a script to automate searching for rules for these licenses and adding these as rules.

For example in https://github.com/aboutcode-org/scancode-toolkit/pull/4478 we had the following licenses added:
[new_licenses.txt](https://github.com/user-attachments/files/21351992/new_licenses.txt)

The steps roughly are:

- [ ] Get the new licenses using synclic (license sync) scripts
- [ ] Get the new license keys (using GitPython: read changed files)
- [ ] Get the license names to search for (might have to search without version numbers too)
- [ ] Use github search API to search for license occurances (remove scancode/licensedb related search results)
- [ ] run license detection to see if we detect these correctly
- [ ] if license not detected correctly add as rules:

I have this working roughly, but this needs some improvements and the new license matcher. Will add the script soon.
