Fix deprecation warning of sbt

[Vescatur]

Building vercors causes the following useless warnings to be printed, we should fix them:

publishArtifact in (Compile, packageDoc) := false

[bobismijnnaam]

This can be fixed by rewriting

publishArtifact in (Compile, packageDoc) := false

to

Compile / packageDoc / publishArtifact := false

I already did this for the main file, but as the subprojects are not always rebuild I didn't see the errors for the subprojects...
