Set versionScheme to PVP in pom.xml for Scala users

[joroKr21]

Is your feature request related to a problem?

Yes, the problem is that grpc-java intentionally breaks binary backwards compatibility in a minor version release:
https://github.com/grpc/grpc-java/releases/tag/v1.59.0

Meanwhile it's fairly standard to assume semantic versioning in the Java ecosystem. See https://semver.org/

Describe the solution you'd like

Scala (sbt) users can benefit from a version scheme property set in the pom.xml which will fail the build when binary incompatible versions of the same library are on the classpath. The version policy which allows breaking changes in minor versions is PVP. So if we add this property to the POM, it will prevent issues:

<properties>
    <info.versionScheme>pvp</info.versionScheme>
</properties>

• See https://pvp.haskell.org/

Describe alternatives you've considered

Additional context

Currently if grpc-java is updated via some transitive dependencies to 1.59.0 while other transitive dependencies remain on older versions we get a binary compatibility issue at runtime: java.lang.ClassNotFoundException: io.grpc.internal.AbstractManagedChannelImplBuilder

This won't help if only the same version is compatible at runtime: #10406 (comment)
