   For SetValue and SetValueEx is says:

   value is a string that specifies the new value.

   but value can also be an integer if the type is DWORD. Here's a test that shows that: https://github.com/python/cpython/blob/3.9/Lib/test/test_winreg.py#L339

   Suggested update:

   value is a string or integer that specifies the new value.

   SetValueEx support using other types as the value, but SetValue does not according to it's defination:

   cpython/PC/winreg.c

   Lines 1719 to 1723 in d7862e9

   	type: DWORD
   	An integer that specifies the type of the data. Currently this must
   	be REG_SZ, meaning only strings are supported.
   	value as value_obj: unicode
   	A string that specifies the new value.
