Description of the problem:
When using the tekton pipeline from the chart, it has its own parmeters and build-args to pass to buildah and this will quickly go out of sync. Instead all the default arguments are better inside one canonical place, the Dockerfile under serverless-workflows/pipeline/workflow-builder.Dockerfile , and all usages shoud point to it.

How reproducible:
100%

Steps to reproduce:

1. Update the serverless-workflows/pipeline/workflow-buidler.Dockerfile with some MAVEN_ARGS_APPEND=foo or QUARKUS_EXTENTIONS=bar

Actual results:
The tekton build must pass the complete values to the dockerfile for the quarkus extensions

Expected results:
The tekton build should use the defaults from the Dockerfile itself without sending any argumets
