chore: migrate to eslint v9

[nguyentoanit]

As announced in our blog post, in ESLint v9.0.0, eslint.config.js is the new default configuration format. The previous format, eslintrc, is now deprecated and will not automatically be searched for.

To address: Update your configuration to the new format following the Configuration Migration Guide. In case you still need to use the deprecated eslintrc config format, set environment variable ESLINT_USE_FLAT_CONFIG to false.

@moltar : Any idea to fix this issue:

ENOENT: no such file or directory, open 'node:path'

I think, Jest Polly couldn't find out the recording directory? 🤔

I think we actually don't need to migrate to ESLint v9 at all for now.
