[lsp-server] 🐞 graphql.config.mjs is not loaded by graphql-language-service-server

### Is there an existing issue for this? - [x] I have searched the existing issues ### Current Behavior `graphql.config.mjs` is note recognized by graphql-language-service-server because of the outdated version of `graphql-config` dependency. - [Current version](https://github.com/graphql/graphiql/blob/main/packages/graphql-language-service-server/package.json#L53) is 5.0.3 - version with .mjs support is https://github.com/graphql-hive/graphql-config/releases/tag/v5.1.0 Is it possible to update it, do not pin exact version, or make a peer dep so that it will auto-update? I am ready to make a PR if either of this options is good. ### Expected Behavior _No response_ ### Steps To Reproduce _No response_ ### Environment * LSP Server Version: latest * OS: MacOS * LSP Client: Zed via zed-extension-graphql ### Anything else? _No response_
