chore: remove the deprecated fields from the promise and resource status

[SaphMB]

Context

In #676, we refactored the kratix status to migrate kratix-specific status properties to a kratix key. To ensure backwards compatibility, the initial status fields remained. This story covers removing those fields.

Acceptance

Deprecated fields

Promise:

• status.workflow
• status.workflows_completed
• status.workflows_failed
• status.kind
• status.version
• status.lastAvailableTime
• status.status

Resource Request:

• status.workflow
• status.workflows_completed
• status.workflows_failed
• status.lastSuccessfulConfigureWorkflowTime

Given I have installed the latest version of kratix
When I install a promise
Then I do not see any of the deprecated fields

Given I have installed the latest version of kratix
When I apply a resource request
Then I do not see any of the deprecated fields
