agentless: Update catalog-info.yaml to prevent skipping or canceling intermediate builds in the pipeline configuration

[nkvoll]

What does this PR do?

Configures the agentless-tests pipeline to not skip or cancel intermediate builds

Why is it important?

Since we're running multiple, possible concurrent tests from main branch on independent releases, these need to be set to false to avoid race condition-like behavior where pipelines are skipped because there is another release starting in another, lower, environment.
