Reuse publishing artifact definition in the Maven export

[yadavan88]

We need to check and fix the issue with publish directive in maven export. It should pass the artifactId, groupId and version number correctly based on the publish directive

[Gedochao]

As for the requirements.
We have a bunch of directives used for the publish command, which allow to define the artifact name, groupId and version.
Those already have directives, but currently aren't used in the --maven export (or --sbt/--mill, for that matter).
It'd make sense to reuse them.

Namely, those are:

//> using publish.organization <org>
//> using publish.name <name>
//> using publish.version <version>
