Remove deprecated check_less_precise

Do we also need to specify check_exact=False? According to the 2.0 docs, rtol is defined as:

Relative tolerance. Only used when check_exact is False.

@pquentin I added the check_exact=False flag, but Github still doesn't think I "addressed the requested changes". Not sure how that works, but I think it's all good now.
