Describe the bug

When using this plugin with ESLint v10, I immediately get an error for the alphabetize rule:

Oops! Something went wrong! :(

ESLint: 10.0.2

TypeError: Error while loading rule '@graphql-eslint/alphabetize': context.getSourceCode is not a function

To Reproduce Steps to reproduce the behavior:

Upgrade to ESLint v10

Run eslint against your code.

Expected behavior

There are no errors.

Environment:

• OS: Linux fedora 6.18.10-402.asahi.fc42.aarch64+16k
• @graphql-eslint/eslint-plugin: 4.4.0
• Node.js: 24.13.0

const baseConfig = defineConfig(
  {

export default baseConfig;
