v0.54.0

Fixed

• IndexOutOfBounds exceptions that took down the process (thanks @Booksbaum!)

Changed

• Update Ionide.LanguageServerProtocol to get new types and fixes (thanks @Booksbaum!)
• Enable several features to be used with untitled/unsaved files (thanks @Booksbaum!)
  • Shift+F1 help, Info Panel, Pipeline Hints, and Line Lens all work now for unsaved/untitled loose files
  • This required an API change to the fsharp/fileParsed notification - it now returns a URI instead of a string
  • This required an API change to the fsharp/pipelineHint request - is is now { TextDocument: TextDocumentIdentifier }
