Stabilize integration tests

[daka1510]

Scope

I checked the integration test results after #114 was integrated.

Problems

1. in-progress matrix jobs are cancelled if any test fails
   • e.g. if integration tests against cloud-production fail, the integration tests against the other environments are cancelled
2. Run integration test - legacy staging fails

Traceback (most recent call last):
  File "/home/runner/work/qiskit-ibm-runtime/qiskit-ibm-runtime/test/utils/decorators.py", line 100, in _wrapper
    raise Exception("Configuration Issue")
Exception: Configuration Issue

3. Run integration test - cloud production fails

qiskit_ibm_runtime.api.exceptions.RequestsApiError: "HTTPSConnectionPool(host='us-east.quantum-computing.us-east.quantum-computing.cloud.ibm.com', port=443): Max retries exceeded with url: /devices (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f45f9c9be20>: Failed to establish a new connection: [Errno -2] Name or service not known'))"

4. Status Badge is broken
