[telemetry-tempest-plugin] Tag ussuri-last & victoria-last

Ussuri and Victoria branches are in Extended Maintenance[1].
Once any stable branch is moved to EM state then, Tempest and
its plugins needs to be released[2] so that we have the compatible
tags to test the EM stable branches[3].

We taged ussuri-last & victoria-last for tempest[4] but forgot to do
it for the tempest plugins. Using the tag 1.6.0 hash which is compatible
for tempest ussuri-last and victoria-last.
