Qiskit dependency needs update

[erichulburd]

Current qiskit dependency is set to ^0.27.0.

• latest version of qiskit is 0.34.2
• Installing qiskit-optimization leads to the following version error:

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
qiskit 0.27.0 requires qiskit-terra==0.17.4, but you have qiskit-terra 0.19.2 which is incompatible.
qiskit-aqua 0.9.2 requires docplex<=2.20.204; sys_platform != "darwin", but you have docplex 2.22.213 which is incompatible.

We should:

• Update qiskit dependency.
• Possibly look to automate dependency updates with renovate
