fix: FBC does not need to generate SBOMs

[arewm]

FBC fragments are not used on their own, instead the catalog is extracted from them and pushed to production. Since we don't use the SBOM, we can just not produce it.

Will this require an update to the default conforma rules? I hear tell that Conforma likes SBOMs for all things, even when they're meaningless.

[arewm]

@nickboldt , yes. This will not pass conforma rules until they are updated.
