Description of problem:

From Ben:

1. Some extensions have missing "Highlights"
2. Some plugins in the extensions marketplace have missing "Highlights" in their expanded view (e.g. LDAP Catalog Integration has the highlight "Add some highlights of the plugins features")
   • Actual: The phrase "Add some highlights of the plugins features" is shown as a Highlight in the plugins expanded view
   • Expected: The plugin should have some genuine highlights that are unique to each plugin
   • Reproduce: Visit various plugins (there are a few). Search GitHib for "Add some highlights of the plugins features" to find them in the /plugins folder.
3. Extensions marketplace doesn't gracefully handle a situation where the marketplace listing has no `icon: ` field in the metadata. In these situations, it should show a default. https://www.figma.com/design/E6C9X3OSVzlWkW7ZsbxN7s/Administration?node-id=8216-14576&t=lyc74PNFpkmVcalR-4
   • Actual: No square is shown by default unless something has been encoded into the metadata. This is inefficient. The grey square must be present in the metadata. Without it no default is shown.
   • Expected: When a plugin does not have a graphical icon encoded in it's metadata a default "plug" icon should be shown. https://www.figma.com/design/E6C9X3OSVzlWkW7ZsbxN7s/Administration?node-id=8216-14576&t=lyc74PNFpkmVcalR-4
   • Reproduce: Remove the `icon: ` stanza encoded in a yaml for a marletplace listing. Once reloaded, the marketplace listing will no longer show a placeholder icon.

From Christoph:

1. Extensions list: Some Red Hat plugins are not verified and misses icons
   • Actual: Icons and verification checkmark is missing
   • Expected: Expect icons and verification checkmark for all RH plugins
