chore: upgrade eslint to v10 when eslint-plugin-react supports it

[BrianLeishman]

Context

Dependabot tried to bump eslint and @eslint/js from v9 to v10 in PR #269, but eslint-plugin-react@7.37.5 only supports eslint up to v9.x:

peer eslint@"^3 || ^4 || ^5 || ^6 || ^7 || ^8 || ^9.7" from eslint-plugin-react@7.37.5

We told dependabot to ignore major versions for both packages:

• @dependabot ignore eslint major version
• @dependabot ignore @eslint/js major version

Action needed

When eslint-plugin-react releases a version with eslint 10 support:

1. Run @dependabot unignore eslint and @dependabot unignore @eslint/js on any open PR (or create a new one)
2. Or manually bump both in package.json:

   "@eslint/js": "^10.x",
   "eslint": "^10.x",
   

3. Run npm install and verify npx eslint . --ext .ts,.tsx passes
