[docs] [issue35007] Minor change to weakref docs

[Frank Millman]

New submission from Frank Millman <frank at chagford.com>:

weakref.WeakKeyDictionary.keyrefs() -

The documentation says 'Return an iterable of the weak references to the keys'.

I was not sure if this would expose me to the 'dictionary changed size while iterating' error, so I checked the source. The source shows that it returns a list, and the docstring says 'Return a list of weak references to the keys'.

I suggest that the documentation be changed to match the docstring.

The same applies to valuerefs().
