Build/Test Tools: Increase timeout-minutes for PHPUnit workflow.

The GitHub Actions workflow responsible for running the PHPUnit test suite is frequently encountering the default `timeout-minutes` value of `20` since the changes in [61438]. The result is that the workflow is consistently unable to finish running and ends up being cancelled.

This bumps the default value to `40` until the overall speed of the build script can be improved.

See #64225, #64227, #64393.
