cbe69e2b - Return `null` from `RootInfo.package` for non-`package:` root libraries (#10033)

Return `null` from `RootInfo.package` for non-`package:` root libraries (#10033) Avoid returning invalid package data from service manager. This is just a simple fix where we return null of a library URI is not a `package:` URI. Fixes https://github.com/flutter/devtools/issues/6734
