doc: improve documentation oc:build

[sunix]

Description

the oc:build part needs rearrangement for instance there is a generic part about build strategy in Openshift build. https://www.eclipse.org/jkube/docs/openshift-maven-plugin#build-openshift it is not clear that kubernetes build is docker build and openshift build is s2i.

Info

• Eclipse JKube version :
• Maven version (mvn -v) :

• Kubernetes / Red Hat OpenShift setup and version :

• If it's a bug, how to reproduce :

• If it's a feature request, what is your use case :

• Sample Reproducer Project : [GitHub Clone URL]

ok so i think i understand:

• kubernetes build is local docker build
• openshift build with docker strategy is remote docker build (in the openshift cluster)

but having say that ... how do we perform a "kubernetes build" ?

[sunix]

this part is wrong:

• It is assuming that it will perform a docker build locally which is wrong.
• it is assuming that docker is the default strategy which is wrong
