docs(deploy): pin pg_isready to POSTGRES_DB and flag the default password (#606)

Add -d snapotter to the guide's Compose healthcheck examples so they match
the shipped compose fix (#595), and note "change this" next to the default
POSTGRES_PASSWORD. English guide only; locale docs regenerate through the
i18n pipeline.
