tkinter: Accept list and tuple in grid sticky option

[melassa]

Added list and tuple to grid sticky option.

Fixes #15507

This is not the only place where sticky is defined. Searching for sticky gives me:

$ git grep -n sticky
tkinter/__init__.pyi:1141:    sticky: str  # consists of letters 'n', 's', 'w', 'e', no repeats, may be empty
tkinter/__init__.pyi:1156:        sticky: str = ...,  # consists of letters 'n', 's', 'w', 'e', may contain repeats, may be empty
tkinter/ttk.pyi:62:    sticky: str  # consists of letters 'n', 's', 'w', 'e', may contain repeats, may be empty
tkinter/ttk.pyi:75:    sticky: str
tkinter/ttk.pyi:149:        sticky: str = ...,
tkinter/ttk.pyi:697:        sticky: str = ...,  # consists of letters 'n', 's', 'w', 'e', no repeats, may be empty

If you need help figuring out which sticky's should be str and which should be str | list[str] | tuple[str, ...], just let me know :)

For example, _GridInfo should be just str:

>>> label.grid(sticky=tuple('nswe'))
>>> label.grid_info()['sticky']
'nesw'
>>> label.grid(sticky=list('nswe'))
>>> label.grid_info()['sticky']
'nesw'

Notebook add() requires it. Layout do not accept list or tuple.

[melassa]

I must open a new PR for Notebook?

[melassa]

All done, for me.

This doesn't work on my system:

>>> from tkinter import ttk
>>> nb = ttk.Notebook()
>>> label = ttk.Label(nb)
>>> nb.add(label, sticky=list('nswe'))
Traceback (most recent call last):
  File "<python-input-3>", line 1, in <module>
    nb.add(label, sticky=list('nswe'))
    ~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/lib/python3.13/tkinter/ttk.py", line 824, in add
    self.tk.call(self._w, "add", child, *(_format_optdict(kw)))
    ~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
_tkinter.TclError: Bad -sticky specification n s w e

Maybe this has to do with Tk version? What's yours?

>>> import tkinter
>>> tkinter.TkVersion
8.6

You are right. Do not work. I made a mistake when testing it. Seems that grid is the only one.

Thanks for working on this! I reverted this back to your earlier version and will merge soon.
