[turkenf]

Description of your changes

In this PR:

• Added crddiff to Makefile
• Updated uptest version to v0.5.0

I have:

• [x] Run make reviewable to ensure this PR is ready for review.

How has this code been tested

crddiff:

• It skips when no changes are made

  

• On line 75 in provider-terraform/apis/v1beta1/workspace_types.go replace

  Name string `json:"name"`

  with

  // +kubebuilder:validation:Optional
  Name *string `json:"name,omitempty"`

  

Caller workflow manually tested on turkenf/uptest and turkenf/provider-terraform
