Build: Fix Gradle warnings

[smarkwal]

Gradle warnings:

• Unresolved imports/types have been detected during analysis. Enable DEBUG mode to see them.
• Deprecated Gradle features were used in this build, making it incompatible with Gradle 8.0.
• You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

Two warnings are reported for sonarqube task:

> Task :sonarqube
The Report.destination property has been deprecated. This is scheduled to be removed in Gradle 8.0. Please use the outputLocation property instead. See https://docs.gradle.org/7.3.3/dsl/org.gradle.api.reporting.Report.html#org.gradle.api.reporting.Report:destination for more details.
The Report.enabled property has been deprecated. This is scheduled to be removed in Gradle 8.0. Please use the required property instead. See https://docs.gradle.org/7.3.3/dsl/org.gradle.api.reporting.Report.html#org.gradle.api.reporting.Report:enabled for more details.

But both properties seem to be used from the SonarQube plugin. There are no usages of properties destination or enabled in the build script.
