Updated the title in the rest file
Shorten filename. Link with very long file name is broken in some URL contexts
such as local builds This change corrects it in local testing but needs
further verification from other contributors.

Cert-manager accepts only short-hand IPv6 addresses.
**Workaround**: You must use the following rules when defining IPv6 addresses
to be used by Cert-manager.
- all letters must be in lower case
- each group of hexadecimal values must not have any leading 0s
(use :12: instead of :0012:)
- the longest sequence of consecutive all-zero fields must be short-handed
with ``::``
- ``::`` must not be used to short-hand an IPv6 address with 7 groups of hexadecimal
values, use :0: instead of ``::``
.. note::
Use the rules above to set the IPv6 address related to the management
and |OAM| network in the Ansible bootstrap overrides file, localhost.yml.
