Add SBOM update mechanism

In the near future, and as the artifacts that the AlmaLinux Build System produces change over time, we should need to provide a way to update already existing SBOMs.

I've made a [question](https://github.com/CycloneDX/cyclonedx-python-lib/discussions/308) to cyclonedx-python-lib guys and apparently, this is something they're already working on. We should keep an eye on them and include their work on that as soon as is released.
