Remove shortnames from Tap API resources (#11816)

The Tap API resource shortnames were colliding with existing Kubernetes
resources (e.g. `po`, `deploy`, etc), causing warnings from kubectl
v1.29.0+.

Remove the shortnames from the Tap APIService handlers.

To validate:
```bash
bin/k3d cluster create

# install latest edge
curl https://run.linkerd.io/install-edge | sh
linkerd install --crds | kubectl apply -f -
linkerd install        | kubectl apply -f -
linkerd check
linkerd viz install    | kubectl apply -f -
linkerd check

# observe shortnames
kubectl api-resources --api-group=tap.linkerd.io

# with kubectl v1.29.0+, observe "Warning: short name..."
kubectl get po

# replace tap image
TAP_IMAGE=$(bin/docker-build-tap)
bin/k3d image load $TAP_IMAGE
kubectl -n linkerd-viz set image deploy/tap tap=$TAP_IMAGE

# verify shortnames are no longer present
kubectl api-resources --api-group=tap.linkerd.io

# with kubectl v1.29.0+, observe no warning
kubectl get po
```

Fixes #11784
