IPv6 addresses may contain a scope id, for example "fe80::1%eth0".

These are usually required for link-local addresses.

bpo-34788 added support for scoped IPv6 addresses, but missed the
"exploded" method:

>>> import ipaddress
>>> ipaddress.IPv6Address('fe80::1%eth0').exploded
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3.9/ipaddress.py", line 394, in exploded
    return self._explode_shorthand_ip_string()
  File "/usr/lib/python3.9/ipaddress.py", line 1824, in _explode_shorthand_ip_string
    ip_int = self._ip_int_from_string(ip_str)
  File "/usr/lib/python3.9/ipaddress.py", line 1705, in _ip_int_from_string
    raise AddressValueError("%s in %r" % (exc, ip_str)) from None
ipaddress.AddressValueError: Only hex digits permitted in '1%eth0' in 'fe80::1%eth0'

Is it out of scope for this bug to add this check for additional invalid IPv6 Scope IDs?

    elif not scope_id or '%' in scope_id or '\x00' in scope_id:

cpython/Lib/ipaddress.py

Line 1859 in 99be1cb

elif not scope_id or '%' in scope_id:

Based on RFC4007, section 11.2, paragraph 5
https://datatracker.ietf.org/doc/html/rfc4007.html#section-11.2

I'd like to work on a fix for this. Is this issue still available?
