Loosen cirq_rigetti pyquil dependency to pyquil-3.*

[ryanhill1]

From: PR Pin cirq_rigetti pyquil dependency to pyquil-3.* #6129:

Problem: pip install cirq --pre may install pyquil-4.0.0rcN which is
incompatible with cirq_rigetti.

Solution: pin the pyquil dependency to "3.*".

but changed pyquil dependency from pyquil>=3.2.0 $\rightarrow$ pyquil~=3.2.0

As of Aug 1 pyquil is on version 3.5.4. I propose that same solution can be achieved with less restrictive pyquil dependency by adding upper bound for version 4.
