Sources of dependencies with capabilities not properly located

[lukebemish]

If you depend on an alternative variant of a module by capability -- for instance,

dependencies {
    modImplementation("dev.lukebemish:mymodtest:0.1.0") {
    capabilities {
            requireCapability("dev.lukebemish:mymodtest-otherfeature")
        }
    }
}

Loom will correctly locate and remap the main jar, but will not correctly locate and remap the sources jar for the module, instead locating that for the main feature of the module -- meaning that correct sources will not be available in IntelliJ at all.
