Update sbt-pekko-paradox

[mdedetrich]

New version does not require all of the workarounds

Also ran

sbt -Dpekko.genjavadoc.enabled=true "docs/paradox; unidoc"

locally to confirm that it works

This plugin adds the ability to generate a list of authors from git log which was Lightbends/akkas method of generating release notes. Due to it relying on an older binary incompatible version of Circe (something which was fixed with latest pekko-sbt-paradox) we can no longer use this plugin.

Since we no longer do this (we have removed all references of running this plugin) its easiest to just remove it for now. I have created an upstream issue 2m/authors#415 if it gets fixed and/or we decide to use it again
