Fix pin-bundle-images.sh to filter openstack-operator before replace

Move filtering from grep to jq to catch openstack-operator paths
before the replace directive substitutes them with local paths.

Issue: The replace directive transforms the path before grep filtering:
  github.com/.../openstack-operator/api => ./api
  grep -v openstack-operator doesn't match './api'

Fix: Filter in jq on .Path before applying .Replace:
  select(.Path | contains("openstack-operator") | not)

This properly excludes openstack-operator and openstack-operator/api(s)
while keeping other operators' /api modules (nova-operator/api, etc).

Prevents CI error:
  Invalid source name docker://EMPTY_SHA:null:https://quay.io/api/v1/repository/./api
