The Push Docker image step is failing post-merge of CAR-1362 with
buildx "unknown" error after layers push successfully. The pre-existing
failure was masked by the cache export error.
Simplify the Push step to match the proven-green cartsnitch/auth/ci.yml
pattern: drop `file: ./Dockerfile` (default) and `build-args:`
(APT_CACHE_BUST is only used to bust apt cache in stage 1 of multi-
stage build, not needed for the rebuilt image). Keep `if: github.event_name
== "push"` to skip on pull_request events.
Diff: 4 lines removed from .gitea/workflows/ci.yml Push step.
