[docs] [issue22822] IPv6Network constructor docs incorrect about valid input

[Chris PeBenito]

New submission from Chris PeBenito:

Here:

https://docs.python.org/3/library/ipaddress.html#ipaddress.IPv6Network

In the constructor documentation, item 1 says:

"""
A string consisting of an IP address and an optional mask, separated by a slash (/). The IP address is the network address, and the mask can be either a single number, which means it’s a prefix, or a string representation of an IPv6 address. If it’s the latter, the mask is interpreted as a net mask. If no mask is provided, it’s considered to be /128.

For example, the following address specifications are equivalent: 2001:db00::0/24 and 2001:db00::0/ffff:ff00::.
"""

However in issue22800 it has been identified that using the expanded netmask (e.g. ff00::/ff00::) is not supported.
