Request to expose error code along with the error message

[SooluThomas]

What is the expected enhancement?

It will be nice to see the error code along with the error message. The current implementation simply returns the error message and there's no way to get the error code. This issue requests for that enhancement.

Thank you!

Background

I'm running

source = """
OPENQASM 4.0;
"""

job = backend.run(source)
result = job.result()
counts = result.get_counts()

and I'm supposed to get error in this case. I get

Traceback (most recent call last):
  Cell In[5], line 6
    result = job.result()
  File /opt/conda/lib/python3.10/site-packages/qiskit_ibm_provider/job/ibm_circuit_job.py:250 in result
    raise IBMJobFailureError(f"Job failed: " f"{error_message}")
IBMJobFailureError: 'Job failed: Internal Error'

It will be nice to be able to see something like IBMJobFailureError: 'Job failed - Error code: 9999; Error message: Internal Error'
