build: don't minimize CRD for `WorkflowEventBinding` and `WorkflowArtifactGCTask`. Fixes #12166

[MasonM]

Fixes #12166. Partial fix for #8190

Motivation

The CRDs under manifests/base/crds/minimal/ are minimized as a workaround for https://github.com/kubernetes/kubernetes/issues/82292. However, WorkflowEventBinding and WorkflowArtifactGCTask are small enough that minimization isn't necessary. Including the full CRD enables users to use kubectl explain to explore the CRD definitions.

Modifications

• Rename removeCRDValidation() to minimizeCRD() so it more accurately describes what it's doing and add comments
• Update minimizeCRD() to only minimize cronworkflows.argoproj.io, clusterworkflowtemplates.argoproj.io, workflows.argoproj.io, workflowtemplates.argoproj.io, workflowtasksets.argoproj.io, since the others are small enough they don't need to be minimized
• Add more details to manifests/base/crds/full/README.md and manifests/base/crds/minimal/README.md

Verification

Ran make start and verified kubectl explain returns spec details for the CRDs:

Click here for kubectl explain --recursive WorkflowEventBinding output

@agilgur5 Thanks for the review! I added additional safeguards in a2ca08019bb42ce5301677de61edc199968589ea. I also discovered there's a secondary issue preventing us from generating the full CRDs for workflows.argoproj.io and a few others: k8s rejects it with errors like this:

The CustomResourceDefinition "workflowtasksets.argoproj.io" is invalid: 
* spec.validation.openAPIV3Schema.properties[spec].properties[tasks].additionalProperties.properties[dag].properties[tasks].items.properties[inline].type: Required value: must not be empty for specified object fields
* spec.validation.openAPIV3Schema.properties[spec].properties[tasks].additionalProperties.properties[steps].items.items: Required value: must be specifiedk

I think this is related to the kubebuilder issues mentioned at https://github.com/argoproj/argo-workflows/pull/3809#discussion_r472383090
