QOL Suggestion: When attempting to parent armature to child in Object mode, show user a warning with the solution

[HeyItsLollie]

I was in Object Mode, and attempted to parent an armature to an empty. This threw the error below:

  File "C:\Users\Zenuel\AppData\Roaming\Blender Foundation\Blender\3.3\scripts\addons\dynamic_parent.py", line 251, in execute
    const = get_last_dymanic_parent_constraint(obj)
  File "C:\Users\Zenuel\AppData\Roaming\Blender Foundation\Blender\3.3\scripts\addons\dynamic_parent.py", line 58, in get_last_dymanic_parent_constraint
    if not obj.constraints:
AttributeError: 'NoneType' object has no attribute 'constraints'

I was able to find the solution via #4: Create the dynamic parent for the armature in Pose Mode instead of Object Mode.

The issue is that the plug-in should catch this, and throw a warning with solution - for example, like how it warns the user when only a single object is selected:

Thanks for suggestion! I've added the message "Armature objects must be in Pose mode" in v1.0.1

Reopened the issue in case you have something to add.

Nothing else to add, thank you for adding it so quickly!
