ConfigParser.items() does not normalize non-string vars like get() #160684

Bug report

ConfigParser.items(..., vars=...) handles non-string overrides differently from get(), although the documented optional arguments have the same meaning.

import configparser

parser = configparser.ConfigParser()
parser.read_dict({'section': {'value': 'original'}})
print(parser.get('section', 'value', vars={'value': 42}))
print(parser.items('section', vars={'value': 42}))

On the current main branch, get() returns '42', but items() raises AttributeError: 'int' object has no attribute 'find'. With 0 or False, items() instead returns an empty string. With raw=True, it returns the unconverted override.

Expected: normalize non-None override values to strings, consistently with get().
