Gopls presently uses hand-coded data types (in internal/lsp/protocol) for communicating with LSP clients. Instead, modify it to use the automatically generated file (internal/lsp/protocol/tsprotocol.go). Replaced files have been put (temporarily) in a directory 'preserve' so readers can compare the old data types with the new ones.
