DBZ-5369 docker-maven-plugin needs to be upgraded for Mac Apple M1

Running 'mvn clean verify' for vitess connector (which includes launch docker for integration tests) would fail when run on an Mac M1 laptop:

    [*ERROR*] Failed to execute goal io.fabric8:docker-maven-plugin:0.31.0:build (start) on project debezium-connector-vitess: Execution start of goal io.fabric8:docker-maven-plugin:0.31.0:build failed: An API incompatibility was encountered while executing io.fabric8:docker-maven-plugin:0.31.0:build: java.lang.UnsatisfiedLinkError: could not load FFI provider jnr.ffi.provider.jffi.Provider

The problem is specific to Apple M1 laptop, and is discussed further in: fabric8io/docker-maven-plugin#1257

This is already fixed in docker-maven-plugin 0.39.1
