ci: never hard-fail deploy-dev/deploy-uat on infra-PR merge outcome (CAR-1216)

The CI bot cannot self-approve cartsnitch/infra main's required human
review, so the in-job auto-merge attempt is structurally impossible
and would always fail with SOME message (checks-pending, then
approvals, then transient errors). Special-casing individual error
strings is fragile — CAR-1212's 'Does not have enough approvals' branch
proved it (deploy-dev run 4999 hit the final else-branch instead).

Make job success depend only on the infra PR being OPENED (and
cs_savannah review requested), NOT on the merge outcome. Replace both
the approvals-elif branch and the final else (exit 1) branch with a
single non-failing branch: emit a ::notice:: with the merge response
and exit 0. The ONLY remaining hard-fail is the empty PR_NUM check
(PR could not be created).

Same change applied symmetrically to deploy-uat.

Refs CAR-1195, CAR-1194, CAR-1212, CAR-1216.
