Support typescript configs

[michaelfaith]

As of ESLint v9.18.0, typescript-based configs have become stable. Currently, when running eslint-interactive with a typescript config, it doesn't find the config file at all. When providing a path using the --config option, it returns an error about the extension not being a known file extension.

✖ Linting...

@michaelfaith Hmmm. I have created a small project to investigate this issue but cannot reproduce the problem.

Can you explain how to reproduce this issue?
