Restore using aqua from release for tutorials job (#5246)
Restore using aqua from release for tutorials job (#5246)

This commit reverts a change made during #5083 to use aqua from master
for the tutorials job. This was done to workaround an aqua bug with
a non-u1/u2/u3 basis that was occuring with the 0.7.x release of aqua.
We typically use the released versions of the libraries in these jobs to
catch potentially breaking changes for the biggest users of the terra
api (the other qiskit elements). This restores this coverage by
switching back to using the aqua release for the job.
