Reverts JetBrains/skiko#1126 with additional fixes

Fixes:
```
org.gradle.internal.execution.WorkValidationException: A problem was found with the configuration of task ':signKotlinMultiplatformPublication' (type 'Sign').
  - Gradle detected a problem with the following location: '/mnt/agent/work/381d14fe560aa354/skiko/build/libs/skiko-0.9.33-javadoc.jar.asc'.

    Reason: Task ':publishAwtRuntimeElementsPublicationToComposeRepoRepository' uses this output of task ':signKotlinMultiplatformPublication' without declaring an explicit or implicit dependency. This can lead to incorrect results being produced, depending on what order the tasks are executed.
```
