Inconsistent Key Naming for IACM workspace.yaml file between docs/code

[sawka-harness]

The docs have a different naming scheme vs the code for the workspace.yaml file. the docs mention "org", "project", and "workspace", but the code uses "_id" on those names.

https://developer.harness.io/docs/infra-as-code-management/cli-commands/cli-iacm-plan/

from the code:

// WorkspaceInfo holds org, project and workspace identifiers from CLI or .harness/workspace.yaml
type WorkspaceInfo struct {
	Org       string `yaml:"org_id"`
	Project   string `yaml:"project_id"`
	Workspace string `yaml:"workspace_id"`
}
