Feature request: filter out BOM artifacts

These are not actually a real dependency, rather they just dictate the version of other dependencies owned by it. This leaks across buildscript classpaths too. For example - `buildscript { dependencies { classpath(platform(libs.coroutines.bom)) } }` will make this show up as a configuration dependency in all subprojects using dependencyGuard as well even if they don't use coroutines. My sense here is that it should filter these.
