Fixed the spelling error in test_xmlrpc where test was misspelled

I changed têšt to test in test_xmlrpc.py, because I thought it wasn't an ASCII character.

Most changes to Python require a NEWS entry. Add one using the blurb_it web app or the blurb command-line tool.

If this change has little impact on Python users, wait for a maintainer to apply the skip news label instead.

I think it was intentional (func name is test_nonascii_methodname encoding='ascii')

https://github.com/python/cpython/blob/main/Lib/test/test_xmlrpc.py#L848-L849

def test_nonascii_methodname(self): 
      try: 
          p = xmlrpclib.ServerProxy(URL, encoding='ascii')
          self.assertEqual(p.têšt(42), 42)

BTW, most changes need a issue number

Not all PR need to be numbered, but I didn't notice the method name, it seems you are right.
