downgrade graphql-config

[lopert]

graphql-config needs to be at 5.1.3, because 5.1.4 is not compatible with node 18, which we need to support in the CLI.

I previously attempted to lock us to 5.1.3 but dependabot opened a PR anyways. See my PR for the full context.

I tested npm install in a JS function that depends on the current main (aka with 5.1.4) and got the same error.

> npm install                                                  ✔ 
npm error code EBADENGINE
npm error engine Unsupported engine
npm error engine Not compatible with your version of node/npm: [email protected]
npm error notsup Not compatible with your version of node/npm: [email protected]
npm error notsup Required: {"node":"20 || >=22"}
npm error notsup Actual:   {"npm":"10.8.2","node":"v18.20.8"}

Next steps

• Hopefully dependabot attempt to re-upgrade this again, and I can mark this dependency as ignored.
• I'll create an issue in this repo for adding a node 18 test to CI to catch future bumps that may break node 18.

Oops! I'm sorry for merging that dependabot PR!

@saga-dasgupta don't worry about it! nothing in the repo shows that we need node 18 compatibility which is the real issue 🙈
