Upgrade kotlin and ksp to latest stable versions

Instructions

Upgraded Kotlin & KSP so this project can receive a KSP memory leak fix https://github.com/google/ksp/issues/2073

I profiled NowInAndroid with a dev local build of KSP to originally test the fix which made it into release 2.0.21-1.0.26. I just profiled it again before and after the upgrade and can verify the metaspace leak is fixed by this change.

Thanks for this.

Just a note for the future, if you update dependencies please also run ./gradlew dependencyGuardBaseline to update the dependency guard files. These make it easy for us to see what's changed in the release build.

We've spent quite a bit of time updating library dependencies recently. Both Kotlin and KSP have been updated as part of updates elsewhere.
