[CI] Use compatible version of heat-tempest-plugin

This is a combination of two patch to fix the gate:

1. Use compatible version of heat-tempest-plugin

heat-tempest-plugin dropped py38 support, hence it cannot be installed
from recent master, so we need to override the checkout to the version
that still supports py38 and compatible to the actual branch.

This is needed both for the grenade job and the functional job, because
these are using the heat-tempest-plugin.

2. Try archive path to download Fedora image

This is a temporal workaround to allow downloading Fedora 37 image
which was moved to the archive path.
