"Resolve error: Tsconfig not found" for extended tsconfigs

I'm getting errors when using `extends` in my `tsconfig.json`. It happens if `extends` is a string, array, references neighboring files, or references `node_modules` files. ```json "extends": [ "@tsconfig/node22/tsconfig.json", "@tsconfig/strictest/tsconfig.json" ], ``` In #400 it appears this has been working in the past, so maybe it's just a user error on my part? There's many layers of package versions, so not sure if it's a regression, or if I'm even opening an issue in the correct project here. **Reproduction steps:** [Minimal reproduction](https://github.com/claabs/eslint-import-resolver-repro) 1. `git clone https://github.com/claabs/eslint-import-resolver-repro.git` 2. `cd eslint-import-resolver-repro` 3. `npm i` 4. `npx eslint index.ts` **Output** ``` /home/charl/projects/eslint-import-resolver-repro/index.ts 1:1 error Resolve error: Tsconfig not found @tsconfig/node22/tsconfig.json at unrsResolve
