Fix spelling error in infoblox namespace

[samccann]

This is what caused the docs builds to fail...

retval = await self._get_galaxy_versions(galaxy_url) File "/home/samccann/new-ansible/lib64/python3.9/site-packages/antsibull/galaxy.py", line 80, in _get_galaxy_versions raise NoSuchCollection(f'No collection found at: {versions_url}') antsibull.galaxy.NoSuchCollection: No collection found at: https://galaxy.ansible.com/api/v2/collections/infobox/nios_modules/versions/

https://github.com/ansible-community/ansible-build-data/blob/main/4/ansible.in#L67 should probably be fixed too

[webknjaz]

and https://github.com/ansible-community/ansible-build-data/blob/main/3/ansible.in#L65

[webknjaz]

as well as https://github.com/ansible-community/ansible-build-data/blob/main/2.10/ansible.in#L62

[webknjaz]

So this is where the problem originated: #73.

thanks @samccann & @webknjaz!

I am sorry for the trouble I caused. Unfortunately, when I saw the commented entry already in place, I was soo happy that I could skip one copy-paste operation that I forgot to proofread the addition.

I unfortunately also didn't notice during review...
