Publish workflow has completed with success should include a better hint how to test the plugin

[christoph-jerolimov]

Currently the publish command creates a success message like this:

Publish workflow has completed with success.

• Published container images:
  • ghcr.io/redhat-developer/rhdh-plugin-export-overlays/backstage-community-plugin-npm:pr_948__1.3.0

(from redhat-developer/rhdh-plugin-export-overlays#948 (comment))

I would be nice if it includes a dynamic plugin yaml example that includes also the used path, like;

Publish workflow has completed with success.

• Published container images:
  • ghcr.io/redhat-developer/rhdh-plugin-export-overlays/backstage-community-plugin-npm:pr_948__1.3.0

You can test this container image in RHDH like this:

plugins: 
  - package: oci://ghcr.io/redhat-developer/rhdh-plugin-export-overlays/backstage-community-plugin-npm:pr_948__1.3.0!backstage-community-plugin-npm-dynamic
    disabled: false
    pluginConfig:
      dynamicPlugins:
        frontend:
          backstage-community.plugin-npm: {}

or you could include some examples

plugins: 
  - package: oci://ghcr.io/redhat-developer/rhdh-plugin-export-overlays/backstage-community-plugin-npm:pr_948__1.3.0!backstage-community-plugin-npm-dynamic
    disabled: false
    pluginConfig:
      dynamicPlugins:
        frontend:
          backstage-community.plugin-npm:

            #       if:
