[lsp-server] 🐞 not working on neovim + coc

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Current Behavior

Auto-completion, "go to definition" and general LSP functionality expectations are not working.

### Expected Behavior

The aforementioned expectations should work.

### Steps To Reproduce

- Install the package and add change the coc.nvim settings as suggested: https://github.com/graphql/graphiql/tree/main/packages/graphql-language-service-cli#lsp-workspace-configuration

- Open a `.gql` or `.graphql` file and trigger the Coc auto-completion (usually `ctrl + space`) and nothing will be returned.

**IMPORTANT**: IntelliJ & https://github.com/neovim/nvim-lspconfig clients work as expected.
