chore: ignore even more configs for dependency submission (#1693)

confirmed ignoring `runtime-internal` suppresses the really
old guava, the `scala-doc-tool` and `scala-tool` configs
currently don't pull in any problematic dependencies but
they should not be relevant to our users either.

Follow-up on #1689
and #1392
