Add support for list parameters in aci_param_set

[Copilot]

Issue

The microsoft/confidential-sidecar-containers repository, which uses this package for testing, was failing with the following error when using version 1.2.2 (while it worked correctly with 1.0.6):

Traceback (most recent call last):
  File "/home/runner/work/confidential-sidecar-containers/confidential-sidecar-containers/tests/attestation/test.py", line 35, in test_attestation
    aci_param_set(
  File "/home/runner/.local/lib/python3.12/site-packages/c_aci_testing/tools/aci_param_set.py", line 28, in aci_param_set
    for key, value in parameters.items():
                      ^^^^^^^^^^^^^^^^
AttributeError: 'list' object has no attribute 'items'

Changes

• Modified aci_param_set() to handle both dictionary and list parameters:
  • Updated type hints to include both formats: dict[str, str] | list[str]
  • Added logic to detect the parameter type and convert lists to dictionaries when needed
  • Maintained backward compatibility with code that passes dictionaries
• Added tests to verify functionality with both parameter formats

Example

The function now works with both formats:

# Dictionary format (original)
aci_param_set(target_path, parameters={"location": "westus"})

# List format (new)
aci_param_set(target_path, parameters=["location=westus"])

Fixes #128.
