Ignore missing / broken link warning does not seem to work in newer sbt versions

[AndyLeGrand]

We've recently switched from sbt 1.6.2 to 1.9.8. Our build workflows now fail due to missing / broken link errors when doing something like [[SomeClass]] in scala doc.
In sbt 1.6.2. this could be fixed / ignored by setting "-no-link-warnings" and scoping to doc / scalaOptions. However this setting does not seem to take effect anymore on sbt 1.9.8.
Is this an intended change? If so, there is no documentation available on this in the scaladoc section.

After some further testing, we found that newer versions still respect this setting, but required scoping to be done a bit different:
sbt 1.6.2. (accepts doc / scalacOptions := Seq( .... "-no-link-warnings"), sbt 1.9.8: requires scoping to Compile / doc / scalacOptions. In any case it would be nice to add a hint regarding this option and how to use it to the Scaladoc section of the docs
