contrib: adjust heptapod CI flavor sizes
Our CI currently runs on a number of different runners, some of which are run
by Clever Cloud.
By setting this environement variable, we're asking for a smaller size runner
for our smaller jobs, which puts less load on the Clever Cloud infrastructure,
while not affecting our overall pipeline times.
