[eslint-plugin-react-hooks] Add ESLint v10 support

[azat-io]

Summary

ESLint v10.0.0 was released on February 7, 2026. The current peerDependencies for eslint-plugin-react-hooks only allows up to ^9.0.0, which causes peer dependency warnings when installing with ESLint v10.

This PR:

• Adds ^10.0.0 to the eslint peer dependency range
• Adds eslint-v10 to devDependencies for testing
• Adds an eslint-v10 e2e fixture (based on the existing eslint-v9 fixture)

ESLint v10's main breaking changes (removal of legacy eslintrc config, deprecated context methods) don't affect this plugin - flat config is already supported since v7.0.0, and the deprecated APIs already have fallbacks in place.

How did you test this change?

Ran the existing unit test suite:

cd packages/eslint-plugin-react-hooks && yarn test

All 5082 tests passed.
