nvim: lsp-utils: Set capabilities

We missed setting this and it gives an error like below when using
HLS and rust-analyzer.

```bash
LSP[rust-analyzer]: Error SERVER_REQUEST_HANDLER_ERROR: "/usr/local/share/nvim/runtime/lua/vim/lsp/_watchfiles.lua:199: attempt to index field 'capabilities' (a nil value)"
