[Bug]: Unknown option testTimeout validation warning when used in project specific config

[saevarma]

Version

29.7.0

Steps to reproduce

Example steps (replace with your own):

1. Clone my repo at https://github.com/saevarma/jest-testtimeout-repro/tree/main
2. yarn
3. yarn test --projects src/packages/sum/jest.config.ts
4. You should see the validation warning displayed in terminal

● Validation Warning:

  Unknown option "testTimeout" with value 1 was found.
  This is probably a typing mistake. Fixing it will remove this message.

  Configuration Documentation:
  https://jestjs.io/docs/configuration

Expected behavior

No warning displayed in the terminal as this should be a known option.

Actual behavior

Validation warning displayed in terminal about unknown option, even though Jest respects and uses the value.

Additional context

No response
