gh-106487: Allow the 'count' argument of str.replace to be a keyword

[hugovk]

Before

>>> "aa".replace("a", "b")
'bb'
>>> "aa".replace("a", "b", 1)
'aa'
>>> "aa".replace("a", "b", count=1)
TypeError: str.replace() takes no keyword arguments

After

>>> "aa".replace("a", "b")
'bb'
>>> "aa".replace("a", "b", 0)
'aa'
>>> "aa".replace("a", "b", count=0)
'aa'
>>> "aa".replace("a", "b", 1)
'ba'
>>> "aa".replace("a", "b", count=1)
'ba'
>>> "aa".replace("a", "b", 2)
'bb'
>>> "aa".replace("a", "b", count=2)
'bb'
>>> "aa".replace("a", "b", 3)
'bb'
>>> "aa".replace("a", "b", count=3)
'bb'

Nice enhancement. It's funny to have Mastodon driven development 😁
