The most significant changes involve the modification of the renaming…

… method in the CTkTabview class and the addition of code to update the _current_name attribute. These changes ensure that the tab renaming process is more efficient and that the connection to the frame is maintained even when a tab is renamed.

Changes:

1. The renaming method in the CTkTabview class has been altered. Instead of removing the old name from the _name_list and appending the new name at the end, the new name now replaces the old name at the same index in the _name_list. This change makes the renaming process more efficient.
2. Code has been added to update the _current_name attribute if the old name matches the current name. This is a crucial change as it ensures that the connection to the frame is not lost when a tab is renamed.
