support for re-writing "-" seperated project names to ClassStyle for main class

[456dev]

Minecraft Development for IntelliJ plugin version

2023.2-1.6.9

Description of the feature request

when creating a project with a name like "abc-test-plugin", the mainclass becomes com.example.abctestplugin.Abc-test-plugin

the feature request is to remove the dashes, and rewrite the main class to something like com.example.abctestplugin.AbcTestPlugin (like how it works if you use spaces in the name)
