Subject: [PATCH] change ipv6 public network cidr on tempest-slow job

Neutron recently enhanced CIDR overlap checks for all the subnets
attached to router including external [1]. This breaks tempest
scenario ipv6 tests which is fixed in tempest by the following
commit [2]. However the fix mentioned in [2] cannot be ported
back to tempest 23.0.0 as rocky is in EM stage.

To fix this, the public IPv6 network CIDR is changed to use
different subnet on the tempest-slow job.

Closes-Bug: #1914037
