fix: added option to specify platform for db in compose (LAION-AI#2725)

related to issue LAION-AI#2721

enables specifying platform for service `db` using environment variable
`DB_PLATFORM`. If left unspecified (silently) defaults to current
behaviour.

this solves the issue where M1 users where unable to use docker-compose
as the `db` service relies on
`ghcr.io/laion-ai/open-assistant/oasst-postgres` (which does not support
`linux/arm64/v8` as plaform).

sadly (afaik) docker-compose does not offer something akin to `docker
--platform` you have to set it in the compose-file.
