Upgrades to Kotlin 2.0.20

[zqirui]

Upgrades to Kotlin 2.0.20

• upgrades multiple dependencies in the version.properties
• adapted to kotlinPoet changes and added package name to member
• removed junit dependency because it can not be used in core packages
• added serialization in the api validation exclude, because it has no api

Closes #866

AS RC19 is released, we could now review and merge this one 😍

[Lysander]

There are some warnings left, that should be handled. I suggest the following changes:

I have run the headless-demo UI tests and everything works fine.

I also started most example apps.

[zqirui]

I applied your patch and did a full build. Build Warnings should be gone now. Thanks!

[Lysander]

Please adapt the versions in the example build.gradle.kts too.

Currently those are still at 1.9.x
