## Details

### Library name and version

Azure CLI 2.76.0

### Describe the bug

Running command `az connectedk8s connect --enable-workload-identity` succeeds, but leaves the extension in state `Creating`. Running `az connectedk8s connect` then `az connectedk8s update --enable-workload-identity` works.

(Note: All commands were also run with `--enable-oidc-issuer`)

### Expected behavior

`az connectedk8s connect --enable-workload-identity` should successfully enable workload identity.

### Actual behavior

`az connectedk8s connect --enable-workload-identity` succeeds (there is an error printed), and leaves workload identity in state `Creating`

### Reproduction Steps

Run command `az connectedk8s connect --enable-workload-identity` and view workload identity extension status.
