Automatic data generation configuration should create remap configurations

[haykam821]

Right now, to add remapped dependencies to the data generation source set created by fabricApi.configureDataGeneration, one must manually specify that remap configurations should be created:

loom {
    createRemapConfigurations(sourceSets.datagen)
}

This use case is common for adding the data generation API only to the data generation source set:

dependencies {
    modDatagenImplementation(fabricApi.module("fabric-data-generation-api-v1", project.fabric_version))
}
