fix(registry): change readiness and liveness probe to httpGet /v2 (#720)

#### What this PR does / why we need it

There are lot of error logging and noise in the registry deployment due
to TLS errors on the probes

- changing the Liveness and Readiness probes `httpGet` on `/v2` path to
avoid TLS handshake errors

Additionally there are noises from OTEL metrics (enabled by default in
registry) but they can be overridden with env via values

```yaml
 - name: OTEL_TRACES_EXPORTER
   value: none
```

This is a very small fix and may not fit into v2 controllers but until
then it would be nice to get this fix in.
