Support gradle version catalogues for run config dependencies

[UpcraftLP]

Currently, NeoGradle does not properly support gradle version catalogues and this syntax will fail to configure:

runs {
    configureEach {
    	// ...
    	dependencies {
    		runtime libs.emi.neoforge
    	}
    }
 }

Error:
Cannot convert the provided notation to an object of type Dependency: map(valueof(DependencyValueSource)).

This can be worked around by converting the dependency to string notation (via libs.emi.neoforge.get()), but implementing proper support would be appreciated.
