Describe the feature

From the ESLint docs:

We are transitioning to a new config system in ESLint v9.0.0. The config system shared on this page is currently the default but will be deprecated in v9.0.0.

There is no timetable for v9 release (see this blog post), however the new config system is "feature complete but not enabled by default" therefore, it seems desireable to think about switching to the new config system.

See:

• https://eslint.org/docs/latest/use/configure/configuration-files
• https://eslint.org/docs/latest/use/configure/configuration-files-new
• https://eslint.org/blog/2023/11/whats-coming-in-eslint-9.0.0
• When is ESLint 9 meant to be released? eslint/eslint#17468
