[Bug] Legal and license information is not provided for Copilot artifacts

[iloveeclipse]

Environment

• OS: irrelevant
• Eclipse Version: irrelevant
• Plugin Version: 0.20.0.202607290210_nightly (but is present in all existing versions)

Describe the bug
The legal and license information is not properly provided for Copilot feature and all Copilot plugins.

Expected

In Eclipse, go to Help -> About -> Installation Details.

1. Under "Features" tab, type "Copilot" in the filter text and click on the "License" button. Instead of showing the license text, a plugin directory listing is shown.

2. Under "Plugins" tab, type "Copilot" in the filter text and observe that on all Copilot plugins the "Legal info" (which usually provides Copiright and license information) is disabled and doesn't provide any information.
