BUG: Deprecation warnings with option_context have incorrect stacklevel #63235
Description
Ref: #63231 (comment)
When a option is deprecated and a user uses a pd.option_context to modify the setting, the warning stacklevel using find_stack_level() points at contextlib rather than the user's calling code. I believe find_stack_level() is not necessary here and the correct stacklevel can be set to a constant to avoid this.
