SuppressedByConditionDocumentableFilterTransformer cannot suppress packages

[owengray-google]

Package-level @hides are common in java source--we have many of them in the Android codebase.

We implement @hide with Marcin's plugin:

class HideTagDocumentableFilter(val dokkaContext: DokkaContext) :
    SuppressedByConditionDocumentableFilterTransformer(dokkaContext) {
    override fun shouldBeSuppressed(d: Documentable): Boolean =
        d.documentation.any {
            (_, docs) -> docs.dfs { it is CustomTagWrapper && it.name.trim() == "hide" } != null
        }
}

However, SuppressedByConditionDocumentableFilterTransformer has

    private fun processClassLike(classlike: DClasslike): DocumentableWithChanges<DClasslike> {
        if (shouldBeSuppressed(classlike)) return DocumentableWithChanges.filteredDocumentable()

But no such clause in private fun processPackage(dPackage: DPackage): DocumentableWithChanges<DPackage> {, which prevents package-level @hides from being processed. (The dPackage has the tag generated and accessible and should work fine.)

This should be a simple one-line change.
I can put up a PR for this if necessary.

Dokka version: 1.6.0-dev-122
