[eprh] Fix config.flat keys to be inferred correctly

[eai04191]

Summary

• fix Bug: [email protected] Type 'ReactHooksFlatConfig | undefined' is not assignable to type 'InfiniteArray<ConfigWithExtends>' #34788

Fixed an issue where the TypeScript type inference for configuration keys was string in the flat config of eslint-plugin-react-hooks.

How did you test this change?

Regardless of this change, the build of eprh does not succeed in my environment, so I have not tested it.

Running: mkdir -p ./compiler/packages/babel-plugin-react-compiler/dist && echo "module.exports = require('../src/index.ts');" > ./compiler/packages/babel-plugin-react-compiler/dist/index.js
 BUILDING  eslint-plugin-react-hooks.development.js (node_dev)

@rollup/plugin-typescript TS7016: Could not find a declaration file for module '@babel/code-frame'. '/Users/eai/ghq/github.com/facebook/react/node_modules/@babel/code-frame/lib/index.js' implicitly has an 'any' type.
  Try `npm i --save-dev @types/babel__code-frame` if it exists or add a new declaration (.d.ts) file containing `declare module '@babel/code-frame';`
