Allow the usage of `-` in project coordinates.

While eu.michael-simons.neo4j.neo4j-migrations-examples is a perfectly valid Group ID, the generator doesn't let me use it. I guess it's due to the fact that you use the same group id to determine package names.

Those two concerns should be separated.

I think it's already supported via the Configure more options link.

I'll have a look. Just tried it via IntelliJ.

Hey @michael-simons, we follow maven conventions: https://maven.apache.org/guides/mini/guide-naming-conventions.html

groupId uniquely identifies your project across all projects. A group ID should follow Java's package name rules.

And Java's package name rules doesn't allow hyphen..

Ok, fair enough. Thank you, Andy!
