RFR: 8360533: ContainerRuntimeVersionTestUtils fromVersionString fails with some docker versions

[Matthias Baesken]

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 failure

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
