telegraf: bump 1.28 -> 1.33 -- docker-ce 29 rejects the pinned API 1.24

Browse Source 
telegraf 1.28's [[inputs.docker]] hardcodes Docker API version 1.24, which
docker-ce >= 29 refuses (min supported API 1.40), so every per-container
stack metric (cpu/mem/net/blkio/health) silently never reached InfluxDB.
DOCKER_API_VERSION is ignored (version pinned in code); newer telegraf
negotiates the API version with the daemon. Verified docker_container_*
measurements land in the telemetry bucket after the bump.
