Ref #26233
Currently Akka fails to build on sbt community build, which runs on JDK 8. Likely it will fail on Scala community build as well due to `--ignore-source-errors`.
This makes the flag conditional based on the running JDK.
It will be useful for Scala toolchain to be able to validate its latest using latest Akka if possible.
* ⇒, →, ←
* because we don't want to show them in documentation snippets and
then it's complicated to avoid that when snippets are
located in src/test/scala in individual modules
* dont replace object `→` in FSM.scala and PersistentFSM.scala
* Update to 1.2.8 and add --ignore-source-errors for javadoc
`--ignore-source-errors` makes 'sbt -Dakka.genjavadoc.enabled=true clean unidoc'
at least output something to target/javaunidoc, though AFAICS it is not
complete (missing index, CSS etc)
* Skip javadoc for scaladsl/GraphDSL.java
As problematic javadoc seems to be generated for
akka.stream.scaladsl.GraphDSL.Implicits.ReversePortsOps
* Enable frames again
