🔧(compose) stop forcing platform for Keycloak PostgreSQL image

Forcing `platform: linux/amd64` for the PostgreSQL
image causes compatibility issues and performance
degradation on Mac ARM chips (M1/M2).
Removing the platform specification allows Docker
to select the appropriate architecture automatically,
ensuring better performance and compatibility.
