cypress.yml: rename COMPOSE_PROFILE to BACKEND_FLAVOR

it used to mean the actual compose profile in pre-oci-env CI,
now it really means a set of predefined conditions and files to use

but now now oci-env started reading COMPOSE_PROFILE from env,
which breaks with

    ERROR - utils.py:42 - standalone from COMPOSE_PROFILE does not exist at /home/runner/work/ansible-hub-ui/ansible-hub-ui/oci_env/profiles/standalone

so just renaming
