Switch to minimal embedded-status

This commit changes the default of embedded-status to minimal status.

Prior to this PR, the `DefaultEmbeddedStatus` is `full`, the pipelineRun reconciler
will populate both `taskruns` and `runs` for `pipelineRunStatus`. With the change
to `minimal`, the reconciler populates `childReferences` instead.

+Currently, the default behavior is default to `status.childReferences` being populated with references to the `TaskRun`s and
 `Run`s, which can be used to look up their statuses.
 
 This behavior can be controlled by changing the `embedded-status` feature flag in the `feature-flags`
 config map. See [`install.md`](./install.md#customizing-the-pipelines-controller-behavior) for more
 information on feature flags. The possible values for `embedded-status` are:
-- `full` - The current default behavior of populating `status.taskRuns` and `status.runs`, without populating `status.childReferences`.
-- `minimal` - Just populate `status.childReferences`, not `status.taskRuns` or `status.runs`.
+- `minimal` - The current default behavior, populate `status.childReferences`, not `status.taskRuns` or `status.runs`.

+- `full` - Populating `status.taskRuns` and `status.runs`, without populating `status.childReferences`.
