Fix LSP not loading .js and .ts files correctly

[witoszekdev]

This PR fixes issue in GraphQL LSP for projects that use graphql.config.ts or graphql.config.js files.

LSP relied on old version of graphql-config, which used cosmiconfig incorrectly by passing a default .js loader to cosmiconfigSync which in turn didn't await the promise and resolved the project's config as {}.

graphql-config 5.1.5+ fixes this by using createJiti for JS/TS loading instead of relying on cosmiconfig's default loaders.

Tested this change in NeoVim + Mason + graphql-language-service-cli on https://github.com/saleor/saleor-dashboard

This PR relies on graphql-config@5.1.5 to fix loading graphql.config.{js,ts} files, but the existing test suite here appears to only exercise YAML/JSON configs (and _loadConfigOrSkip tests don’t validate JS/TS config parsing). Please add a regression test that loads an actual graphql.config.js and/or graphql.config.ts fixture and asserts the config is read correctly, to prevent this bug from returning on future dependency updates.

[Copilot]

The changeset marks graphql-language-service-cli for a patch release, but this PR doesn’t change that package (and it doesn’t directly depend on graphql-config). Consider removing it from the changeset, or update the CLI’s dependency constraints in a way that makes this release meaningful (e.g., if you intend to pin/bump graphql-language-service-server there).

Suggested change

'graphql-language-service-cli': patch

[witoszekdev]

Not sure how to correctly bump version of graphql-language-service-cli since we will have fresh lockfile only after fixes for graphql-language-service are released
