How can I re-declare variants for a configuration using gradle kotlin dsl?

I am trying to setup a basic app running quarkus 3.4.3 and javafx 21.0.1 using gradle 8.4 with kotlin dsl as the build tool. As soon as I apply the quarkus plugin, I get an error when the build tries to resolve the files for the configuration:

Execution failed for task ':jfxapp:quarkusGenerateCode'.
> Could not resolve all files for configuration ':jfxapp:quarkusProdBaseRuntimeClasspathConfiguration'.
   > Could not resolve org.openjfx:javafx-controls:21.0.1.
     Required by:
         project :jfxapp
      > Cannot choose between the following variants of org.openjfx:javafx-controls:21.0.1:
          - linux-aarch64Runtime
          - linuxRuntime
          - mac-aarch64Runtime
          - macRuntime
          - runtime
          - winRuntime
        All of them match the consumer attributes:
          - Variant 'linux-aarch64Runtime' capability org.openjfx:javafx-controls:21.0.1:
              - Unmatched attributes:
                  - Provides org.gradle.category 'library' but the consumer didn't ask for it

It seems I will have to fix this via the project configuration. The javafx-gradle plugin states the following regarding variants:

// Approach 1: Explicit Variant
// The following snippet will let you add attributes for linux and x86_64 to a configuration
configurations.someConfiguration {
    attributes {
        attribute(Usage.USAGE_ATTRIBUTE, objects.named(Usage, Usage.JAVA_RUNTIME))
        attribute(OperatingSystemFamily.OPERATING_SYSTEM_ATTRIBUTE, objects.named(OperatingSystemFamily, "linux"))
        attribute(MachineArchitecture.ARCHITECTURE_ATTRIBUTE, objects.named(MachineArchitecture, "x86-64"))
    }
}

// Approach 2: Copy existing configuration into another configuration
configurations.someConfiguration  {
    def runtimeAttributes = configurations.runtimeClasspath.attributes
    runtimeAttributes.keySet().each { key ->
        attributes.attribute(key, runtimeAttributes.getAttribute(key))
    }
}

but I an unable to make it work.
Can anyone tell me how to fix this issue? I cannot upload files here because I am a new user, but I am sharing the link of the sample app via a link to a bug report I filed in quarkus:
sample project
Thank you!

configurations.someConfiguration {
    attributes {
        attribute(Usage.USAGE_ATTRIBUTE, objects.named<Usage>(Usage.JAVA_RUNTIME))
        attribute(OperatingSystemFamily.OPERATING_SYSTEM_ATTRIBUTE, objects.named<OperatingSystemFamily>("linux"))
        attribute(MachineArchitecture.ARCHITECTURE_ATTRIBUTE, objects.named<MachineArchitecture>("x86-64"))
    }
}

// Approach 2: Copy existing configuration into another configuration
configurations.someConfiguration {
    val runtimeAttributes = configurations.runtimeClasspath.get().attributes
    runtimeAttributes.keySet().forEach { key ->
        attributes.attribute(key as Attribute<Any>, runtimeAttributes.getAttribute(key))
    }
}
