Go binaries that currently get `(devel)` as the version should instead stub `UNKNOWN` based on the compliance policy

[westonsteimel]

What would you like to be added:

With the recent introduction of raising up unknowns in the SBOM along with a compliance policy for determining how the unknown components should be represented, I think it would be good to treat go binaries with a value of (devel) in the same way as unknown versions for all other ecosystems.

Why is this needed:

To unify the treatment of unknown values across all ecosystems.

Additional context:
This would likely be coupled with related changes on the grype side most of which is discussed in https://anchorecommunity.discourse.group/t/grype-reporting-vulns-for-unknown-versions/174/7

Dev notes:

Instead of setting the main module to (devel) here:

syft/syft/pkg/cataloger/golang/parse_go_binary.go

Line 406 in 453b187

Version: devel,

, we have no version set on the returned package, and let the "known-unknowns" logic handle it.
