Create a GitHub action to create an SBOM

[AyanSinhaMahapatra]

Create a GitHub action using scancode.io:

• use package/dependencies/vulnaribility data from scancode.io
• to output a SPDX/CycloneDX SBOM
• upload this as an artifact created by the action (like artifacts created on tag push/release)

I'm not even doing it for GSOC or not, if you could just assign me to fix the raised issue I'd be highly gratefull

@asmitrai we do not assign issues, but feel free to contribute and ask questions on the issue/implementation details
