Missing type declaration of the `result` paramter passed into `setResult(result)` in `Plugin Manager/Script.md`

https://github.com/AdobeDocs/uxp/blob/47510097aaf62876dfe00a01e00461ce5018e6cc/src/pages/uxp/reference-js/Modules/uxp/Plugin%20Manager/Script.md?plain=1#L25-L31

> "Host defines the contract on as to what can be returned from scripts and its format."

This makes sense as internal documentation, but doesn't provide any value for 3P developers.

Start in src/pages/uxp/reference-js/Modules/uxp/Plugin Manager/Script.md around lines 25-31 and review the setResult(result) documentation. Investigate the host-defined contract for the result parameter, then update the page so third-party developers can determine its type and format. Done means the parameter documentation is actionable rather than referring only to an internal host contract.
