Change Request: remove support for jiti < 2.2.0

[fasttime]

ESLint version

v9

What problem do you want to solve?

Currently ESLint requires jiti >= 2 to load TypeScript configuration files. Versions of jiti prior to 2.2.0 have issues that can cause compatibility problems when configs load certain plugins (see #19413). These versions have low download rates (https://github.com/eslint/eslint/pull/19697#discussion_r2077129444), and they add complexity to production logic and testing.

What do you think is the correct solution?

Remove support for jiti version before 2.2.0. Only jiti >= 2.2.0 should be supported.

Since I’ve experienced similar issues while maintaining my own custom packages, I’m 👍 with this decision.

I think it makes sense to do this in the v10 timeframe. :+1:

[fasttime]

I don't see any objections, so marking as accepted. We can discuss the details during the implementation.

TSC group has confirmed this for v10

I could take this, if you'd want help?
