Python: str representation of SKFunctions are very verbose

[moonbox3]

Describe the bug
After upgrading to Pydantic 2, the str representation of SKFunctions are very verbose while running Notebooks:

{'lowercase': SKFunction(FUNCTION_PARAM_NAME_REGEX='^[0-9A-Za-z_]$', FUNCTION_NAME_REGEX='^[0-9A-Za-z_]$', SKILL_NAME_REGEX='^[0-9A-Za-z_]$'),
'trim': SKFunction(FUNCTION_PARAM_NAME_REGEX='^[0-9A-Za-z_]$', FUNCTION_NAME_REGEX='^[0-9A-Za-z_]$', SKILL_NAME_REGEX='^[0-9A-Za-z_]$'),
'trim_end': SKFunction(FUNCTION_PARAM_NAME_REGEX='^[0-9A-Za-z_]$', FUNCTION_NAME_REGEX='^[0-9A-Za-z_]$', SKILL_NAME_REGEX='^[0-9A-Za-z_]$'),
'trim_start': SKFunction(FUNCTION_PARAM_NAME_REGEX='^[0-9A-Za-z_]$', FUNCTION_NAME_REGEX='^[0-9A-Za-z_]$', SKILL_NAME_REGEX='^[0-9A-Za-z_]$'),
'uppercase': SKFunction(FUNCTION_PARAM_NAME_REGEX='^[0-9A-Za-z_]$', FUNCTION_NAME_REGEX='^[0-9A-Za-z_]$', SKILL_NAME_REGEX='^[0-9A-Za-z_]*$')}

To Reproduce

1. Get latest code or ref the latest SK Python package (0.4.2.dev0).
2. Run the 05-using-the-planner notebook.
3. In the cell where we create an SKFunction like:

from semantic_kernel.core_skills import FileIOSkill, MathSkill, TextSkill, TimeSkill
kernel.import_skill(MathSkill(), "math")
kernel.import_skill(FileIOSkill(), "fileIO")
kernel.import_skill(TimeSkill(), "time")
kernel.import_skill(TextSkill(), "text")

4. You will see after running the notebook cell:

{'lowercase': SKFunction(FUNCTION_PARAM_NAME_REGEX='^[0-9A-Za-z_]$', FUNCTION_NAME_REGEX='^[0-9A-Za-z_]$', SKILL_NAME_REGEX='^[0-9A-Za-z_]$'),
'trim': SKFunction(FUNCTION_PARAM_NAME_REGEX='^[0-9A-Za-z_]$', FUNCTION_NAME_REGEX='^[0-9A-Za-z_]$', SKILL_NAME_REGEX='^[0-9A-Za-z_]$'),
'trim_end': SKFunction(FUNCTION_PARAM_NAME_REGEX='^[0-9A-Za-z_]$', FUNCTION_NAME_REGEX='^[0-9A-Za-z_]$', SKILL_NAME_REGEX='^[0-9A-Za-z_]$'),
'trim_start': SKFunction(FUNCTION_PARAM_NAME_REGEX='^[0-9A-Za-z_]$', FUNCTION_NAME_REGEX='^[0-9A-Za-z_]$', SKILL_NAME_REGEX='^[0-9A-Za-z_]$'),
'uppercase': SKFunction(FUNCTION_PARAM_NAME_REGEX='^[0-9A-Za-z_]$', FUNCTION_NAME_REGEX='^[0-9A-Za-z_]$', SKILL_NAME_REGEX='^[0-9A-Za-z_]*$')}

Expected behavior
We don't need to expose the SKFunctionBase attributes. Something like this should be fine:

'lowercase': SKFunction()
