docstring missing for Sampler.close()

[hhorii]

Informations

• Qiskit Aer version:
• Python version:
• Operating system:

What is the current behavior?

Since Qiskit/qiskit@75673c7 of Terra, close() is removed from Sampler but AerSampler has close() with assuming that docstring exists in its base class. This mismatch causes Lint error: qiskit_aer/primitives/sampler.py:161:4: C0116: Missing function or method docstring (missing-function-docstring).

Steps to reproduce the problem

Just run lint.

What is the expected behavior?

Pass Lint.

Suggested solutions

Add docstring to close() or change Sampler implementation in Aer.
