fix(ci): github action runner disk full error #641

Added a docker resource pruning call to the
test case that was triggering the disk full issue
while pulling the Fabric AIO image necessary
for it's operation.

It is expected that this error will crop up in the future with different test cases and if and when that
happens we can add more of the same to
those tests as well, but for now, I did not want to
make this change to every single test case since
it wasn't strictly necessary and a better solution may
come along in the near future as well.

Fixes #641
