raboof opened a new issue, #1129:
URL: https://github.com/apache/incubator-pekko/issues/1129
graphviz produces errors during the generation of embedded svgs in the 2.12
scaladocs.
you can reproduce this with e.g. `sbt ++2.12 persistence-tck/doc`.
diagnosing by adding `-diagrams-debug` to the scaladoc options in
`project/Doc.scala`, we get some more diagnostics:
```
model contains 36 documentable templates

The graphviz dot diagram tool has malfunctioned and will be restarted.
The following is the log of the failure:

I'm using graphviz 9.0.0, and passing that graph to dot manually works fine.
Also 2.13 docs appear to be fine.
Perhaps we should just disable scaladoc diagrams for 2.12?
