ESLint added experimental support for typescript config files since 9.9.0, and as of 9.18.0 that support is stable. This PR add ts/mts/cts to the list of known eslint config files, and adds the same extensions to config file generators
Current Behavior
When using the eslint executor with a ts file, returns error "When using the new Flat Config with ESLint, all configs must be named eslint.config.js or eslint.config.cjs and .eslintrc files may not be used. See https://eslint.org/docs/latest/use/configure/configuration-files"
When using the eslint plugin, the inferred task is not created for projects that do not have a non-ts eslint config.
Workarounds
Expected Behavior
When using the eslint executor with a ts file, no error is thrown.
When using the eslint plugin with a ts file, the inferred task is created.
