Fix AxonInfo initialization in get_mock_neuron function

[VolodymyrBg]

Updated the AxonInfo initialization in the get_mock_neuron function to use the correct parameters according to the AxonInfo class definition. Specifically:

• Removed incorrect 'block' parameter
• Added required 'hotkey' and 'coldkey' parameters
• Changed 'ip' parameter from integer 0 to string "0.0.0.0"
  This fixes the TODO comment that indicated the AxonInfo implementation wasn't working correctly.

I'd use here get_mock_hotkey and get_mock_coldkey methods instead of some_hotkey and some_coldkey strings.

Sorry for confusing you. I ment get_mock_hotkey and get_mock_coldkey methods such we have in that module. Not just a string.
