✨ (eslint) NICE-129 continued flat config upgrade

[JeromeFitz]

typescript-eslint

Continue migration to eslint@9

New Rules

This has the potential to be a b/r/e/a/k/i/n/g change, reason being there seems to be some new rules due to moving packages. Specifically around:

• @typescript-eslint/consistent-type-definitions: Use an interface instead of a type
• no-extra-boolean-cast: Redundant double negation
• no-empty-pattern: Unexpected empty object pattern

These all should probably be fixed but will be ignored for now and addressed later.

Applications importing this package will need to do the same. At the risk of bumping a major every single time we upgrade package(s) from eslint@8 => eslint@9 we are going to use @jeromefitz/eslint-conifg@4 as a holding pattern.

• Updated README with above

Packages

Add

• @types/eslint__js
• @eslint/compat
• @eslint/js
• eslint-plugin-import-x (migrated from eslint-plugin-import)
• typescript-eslint

Remove

• eslint-plugin-import (migrated to eslint-plugin-import-x)
• typescript-eslint/eslint-plugin

Please Note: This is continual as the eslint ecosystem continues to slowly (but surely) move to eslint@9. There are some hacks currently to be able to account for config|plugin that are @8. They will continue to be removed / updated.

Refactor

Needed to add back some rules that have gone away from recommended plugins/configs.

Apply Formatting

• Add @todo(NICE-129) to identify that we should update these, but should not within this PR

Configuration

• Override @typescript-eslint/parser@7.15.0
• Renovate: eslint rework
• Turbo: Move to outputLogs: "new-only" (away from errors-only)

Closes #1507
