exclude entitlements from CurrentWorkspaceID Me probe

CurrentWorkspaceID issues `GET /api/2.0/preview/scim/v2/Me` to read the
X-Databricks-Org-Id response header. The Me endpoint computes
User.Entitlements by default - a scan whose cost scales with the total
number of entitlement grants in the workspace - and CurrentWorkspaceID
never reads the body at all. Ask the server to skip the attribute.
