Fix publishing config

tasks.withType<AbstractPublishToMaven>().configureEach { ... }
runs the lambda when each matching task is created.
The nmcp plugin creates publishKotlinFakerBomPublicationToNmcpRepository
but doesn't bind the publication property immediately — it's set later.
Eagerly calling publication.name during configuration hit the null.
Moving it into onlyIf defers it to execution time, when the publication is guaranteed to be set.
