What is the purpose of this pull request?

In this PR, I added the missing name property to the recommended config.

The @eslint/markdown and @eslint/js plugins now both include a name property in their recommended or all configurations, but it's missing from @eslint/json's recommended configuration.

• https://github.com/eslint/eslint/blob/main/packages/js/src/configs/eslint-recommended.js#L8
• https://github.com/eslint/eslint/blob/main/packages/js/src/configs/eslint-all.js#L8

Therefore, I added the name property to keep core ESLint configurations consistent.
