Fix textDocumentSync server capability
Previously the textDocumentSync property was malformed and not according to spec.
It seemed vscode did the right thing and fell back to sending both didChange and didSave notifications anyways.
Neovim didn't, so we didn't receive any didSave notifications. Now everything is working as expected with neovim and vscode.
