Updated the comment for `precomputeResourcesContainment`.
Updated the comment for `precomputeResourcesContainment`.

`precomputeResourcesContainment` used return a `bool`, but was modified
to return `void` since the `bool` is already included in the `result`.
This fixes the corresponding comment that was not adjusted accordingly.
