Added list and tuple to grid sticky option.

[Akuli]

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.

I must open a new PR for Notebook?

[melassa]

All done, for me.
