feat: have "formulation" as part of the BOM - MBOM

## Is your feature request related to a problem? Please describe.

CycloneDX 1.5 supports formulation: https://cyclonedx.org/guides/sbom/formulation
This could be used to document how webpack was configured and how it compiled/packed the results.

## Describe the solution you'd like

* if target is spec 1.5, then the result should contain information how webpack built the result.
* the details are to be discussed here:
* add Manufacturing Bill of Materials (MBOM) to the capabilities/keywords
* ... to be continued & discussed

## Describe alternatives you've considered

--

## Additional context

need to POC/investigate what information can be gathered from webpack, and if the information qualifies for "CDX formulation"
