On Linux ppc64le RHEL 8, we have such a docker version :
docker --version
Docker version v25.0.3, build 4debf41

Unfortunately, the leading 'v' is not expected in ContainerRuntimeVersionTestUtils fromVersionString so we get an exception.

Probably we should simply skip the leading 'v' .
Also the appended build info has to be considered.

Example :
TEST: jdk/internal/platform/docker/TestDockerMemoryMetricsSubgroup.java
TEST RESULT: Failed. Execution failed: `main' threw exception: java.lang.RuntimeException: Failed to parse container runtime version: Docker version v25.0.3, build 4debf41
