[VSCODE] Manifest generator tooltips should provide info instead of opening browser

[nmetulev]

Tell us about your feature idea

The tooltips in the manifest generator open a link in the browser and take the developer outside of vscode. The tooltips should provide basic information and allow the developer to click a link to get more information if needed. Opening the browser for each tooltip introduces a lot of back and forth.

Do you have an implementation or a solution in mind?

We could take a one or two sentence description of the property and use that for the tooltip with a link to the full documentation

Have you considered any alternatives?

Alternatively, an inline flyout could load the documentation in the manifest generator. However, this solution is more work and the solution above can provide a cleaner experience.
