Update Gradle and other dependencies

[alexander-yevsyukov]

This PR updates the version of Gradle to 9.1.0, applying the workaround for the issue with License Report. The workaround is in disabling generateLicenseReport tasks in build files java-tests/build.gradle.kts and proto/build.gradle.kts. proto and java-tests are interim parent Gradle projects, which causes the problem with the configuration resolution under Gradlel 9.0.0 and on.

Other notable changes

• Latest config was applied brining new versions of local and external dependencies.
• NumberConversion was converted to Kotlin to address the warning of exposing package-access API.
