refactor: handle updated signature of lsp.start_client (#3126)

https://github.com/neovim/neovim/pull/28478 changes the signature of
start_client to return two values: client_id or nil and error message or
nil. start_client no longer calls vim.notify directly, so if there is an
error we must call vim.notify ourselves.
