Hi

I like your library and tool and use it quite some time.
I have found out that in some case there might be a minor issue.

I have (for reasons what ever) a IPv6 Link Logical Adress.

I checked the issue with different constraints, scraping for many time solves the issue.
But when scraping for short time period, all is fetched!
Everything is fine, except for the "interface_index" in Service Discovery info.

I think a simply fix might help here, I found out that the check is only for the length of the ip if it is 16 or not.
But It can be simply >= 16.

Please see here: https://github.com/python-zeroconf/python-zeroconf/blob/master/src/zeroconf/_services/info.py#L252

version is >= 3.9.0 see: sys.version_info(major=3, minor=10, micro=12, releaselevel='final', serial=0)

If this is >= 16 it should work for short scraping.

My Test Program shows it simply here:

`import ipaddress
ip6adr = str(ipaddress.IPv6Address(ip))
ip = "fe80::22b0:f7ff:fe07:2178"
ip6adr = str(ipaddress.IPv6Address(ip))
if ipaddress.ip_address(ip6adr).is_link_local:
print("Interface number is required!")

print(len(ip))
`

This shows that it can be a Link Logical Address with a length greater than 16.
I have to scrape very long time to be luckily and get the interface_index or often it is not present.

But in my scenario, I simply scrape 3 times not more, because of time constraints.
May I missed one option?
Force interface_index to be present oder something?

greetings
