Fix: Correct comment for push() and add setSwitchDebounceDelay(int)

[ivanao92]

The comment for push() function was mistakenly copied from the rotate() function, leading to inaccurate documentation. Updated the comment to accurately describe the behavior of push().

Additionally, added the setSwitchDebounceDelay(int) function to allow customizing the debounce time for the switch, while maintaining compatibility with existing projects.
