Remove dependency on sbt-dependency-graph

[mkurz]

Turns out, this line

sbt-paradox-dependencies/build.sbt

Line 17 in a0b8f9d

addSbtPlugin("net.virtual-void" % "sbt-dependency-graph" % "0.10.0-RC1")

is not needed anymore since sbt 1.4, because it's build in now.
See https://www.scala-sbt.org/1.x/docs/sbt-1.4-Release-Notes.html#sbt-dependency-graph+is+in-sourced

Actually for advanced usage you can replace it with

addDependencyTreePlugin

However it's not that easy, because you make use of apis here:
https://github.com/search?q=repo%3Alightbend%2Fsbt-paradox-dependencies%20ModuleGraph&type=code

which in sbt are now internal...
(Maybe it's easy to fix, but didn't try, leave that up to you)

I guess we will discontinue this plugin.
