Closes #33181 (closed)
Since this option is not working already, dropping it should not be a breaking change IMO.
Not adding the fallbackPlacements here in place of the flip option because the Popper's default value for this option is not customized by Bootstrap. Bootstrap is not customizing the value for fallbackPlacements because it is not needed: #32843. Users can change the flipping behavior by passing the array in the fallbackPlacements option directly in Popper's config. (For example, flipping behavior can be disabled by passing an empty array to the fallbackPlacements option.)
