Error: File '../../tsconfig.base' not found

I started getting this error after bumping the version from `1.18.5` to `1.23.0`. It seems like it's coming from `find-cypress-specs` but I couldn't pinpoint it.

```

Reproduce the reported CI failure and inspect find-cypress-specs/src/index.js and cypress-split/src/parse-inputs.js, where the stack trace enters the affected dependencies. Compare behavior between versions 1.18.5 and 1.23.0, then verify that the Cypress setup completes without the missing ../../tsconfig.base error.
