Inconsistent `exportselection` type in tkinter

[MarcellPerger1]

The types for the exportselection argument in tkinter methods are inconsistent.
In 7 out of the 8 occurrences, the type is bool, but in the 1 other occurrence (in Listbox.__init__) the type is int:

typeshed/stdlib/tkinter/__init__.pyi

Line 2113 in 9d90eeb

exportselection: int = ...,

It seems that some code passes 0 or 1 instead of a bool (see #4765) so it would make sense for all of these types to be int. Or bool | Literal[0, 1] is probably better.

Some booleans were changed (very inconsistently) to ints in #4765.

I don't like the idea of changing more exportselection parameters (or other parameters) to match this. I see supporting int as a legacy thing that most users don't want. But because #4765 was created, I assume that someone still needs it, so we also can't just change them all to bool.

If you want, we can switch to using bool | Literal[0, 1] instead of int.

I changed a few ints to bool | Literal[0, 1] in #11412. I will add more Literal[0, 1] into specific places when someone wants it, but I won't litter it all over tkinter for consistency.
