Don't publish build-helpers, use it directly

Fixes https://youtrack.jetbrains.com/issue/CMP-1339/Change-description-of-androidx-artifacts-in-Maven-Central-stage

We need some changes in it:
https://youtrack.jetbrains.com/issue/CMP-7198/Maven-Central-publication-publishes-old-artifacts-for-Core-Bundle
https://youtrack.jetbrains.com/issue/CMP-1339/Change-description-of-androidx-artifacts-in-Maven-Central-stage

and the current workflow is complicated:
- make changes
- publish this as a library in the dev repo
- add this as a dependency in some Gradle project (Example https://github.com/JetBrains/compose-multiplatform-core/blob/2d8c5f479f590305b9fedc744e00fdc9c276bbb9/mpp/build.gradle.kts#L286)
- Run the gradle task on CI from compose-multiplatform-core project
```
clone compose-multiplatform-core
./gradlew reuploadArtifactsToMavenCentral --info --stacktrace -Pmaven.central.sign=true -Pmaven.central.group=$group -Pmaven.central.stage=$stage -Pmaven.central.version=$version -Pmaven.central.staging.close.after.upload=true
```
This task also doesn't use any of `compose-multiplatform-core` info, so it is overhead to store it as part of this project.

Now we just change some code, and it is already can be run by CI.
