vm templates show up in standalone template catalog

Description of problem:

VM templates are OpenShift template resources and are showing up in the standalone template catalog. They get filtered out of the main catalog because of the work done in https://issues.redhat.com/browse/ODC-5177

This is insufficient because the vm template provider isn't run when viewing the standalone template. The work done in ODC-5177 is still valid to allow for overrides. Eg provide a customized experience for a specific template.

Prerequisites (if any, like setup, operators/versions):

requires https://github.com/openshift/console/pull/7188

install OpenShift Virtualization operator

Steps to Reproduce

1. create a VM template
2. go to dev catalog
3. click on templates type
4. search for vm template

Actual results:

vm template is found

Expected results:

vm templates should not be found in templates catalog

Reproducibility (Always/Intermittent/Only Once):

always

Build Details:

not available in build until PR is merged for vm templates

Additional info:

The idea of adding a filter which receives all the items of a given type will not work because items are normalized into CatalogItem which lacks details about the origin of the resource which created the CatalogItem.
