⭐️ Add tags to objectref (#5083)

* ⭐️ Add tags to objectref

We can use the tags to provide additional metadata for variants like
what icon to use and what title to show

An example:
```
queries:
  - uid: mondoo-edr-policy-ensure-edr-agent-is-installed
    title: Ensure EDR Agent is installed
    variants:
        - uid: mondoo-edr-policy-ensure-edr-agent-is-installed-macos
          tags:
            mondoo.com/filter-title: macos
        - uid: mondoo-edr-policy-ensure-edr-agent-is-installed-linux
          tags:
            mondoo.com/filter-title: linux
        - uid: mondoo-edr-policy-ensure-edr-agent-is-installed-windows
          tags:
            mondoo.com/filter-title: windows
```
