Fix TypeError in help command by handling mixed parameter types for sorting

[shubhamsugara22]

Summary:

This PR addresses the issue where the st2 run action pack.action -h command fails with a TypeError: '<' not supported between instances of 'str' and 'int'. The error occurs when sorting action parameters that have a mix of names (strings) and positions (integers). In Python 3, comparing these types directly causes a failure.

Root Cause:

The sorting function attempts to sort action parameters by either the position attribute (if present) or the name. In some cases, position is an integer while name is a string, leading to a type comparison error in Python 3.

Fix:

The _get_parameter_sort_value method has been updated to:

• Convert the position attribute to a string (if it exists) for consistent sorting.
• Fallback to sorting by the name when position is not available.
• Ensure Python 3 compatibility by avoiding mixed-type comparisons during parameter sorting.

Fixes #5130

@nzlosh @cognifloyd can you check getting lint error again and again adjusted the file according to black format still logic is fine but because of lint check is failing

[shubhamsugara22]

@amanda11 @nzlosh @cognifloyd Can you review this request ?

[cognifloyd]

Converting position to string will change the sort order; for example "10" sorts before "2". So, I'm concerned about merging this solution.

[shubhamsugara22]

@cognifloyd made some changes but does it look like , is this change feasible to apply if yes , then can discuss how to proceed further otherwise , we can close if the issue doesn't look like solving

[cognifloyd]

The logic is now pretty much the same as before.

I think a clean way to solve this would be to create a custom object wrapper that handles sorting comparisons. The object would wrap either name or position (a str or int). When the objects are compared with each other, an int should be sorted before a str, and if the types are the same, use the standard python comparison.

[shubhamsugara22]

Something like this (ignore the class it can be updated later & mainly focus on logic) @cognifloyd

class ParameterWrapper:
    def __init__(self, value):
        self.value = value

    def __lt__(self, other):
        # Prioritize int values over str values
        if isinstance(self.value, int) and isinstance(other.value, str):
            return True
        if isinstance(self.value, str) and isinstance(other.value, int):
            return False
        # Use natural ordering if types are the same
        return self.value < other.value

    def __repr__(self):
        return f"ParameterWrapper({self.value})"

  and update the existing function

          if parameter:
        position = parameter.get("position")
        # Return a ParameterWrapper object for consistent sorting behavior
        return ParameterWrapper(position if position is not None else name)
