Change Postgres auth method in docker-compose

[gmsantos]

If you create a breeze environment with postsgres 14, the new default auth method configured in the postgres image is not compatible with ARM64 builds (like Mac M1) by default. For local environments, I think it is okay to downgrade the auth method to be more compatible with some scenarios.

Steps to reproduce:

• Stop current breeze env breezze stop
• Run a new env with breeze --backend postgres --postgres-version 14
• Execute some command that interact with database (like airflow db reset)

root@ddb098ff425c:/opt/airflow# airflow db reset
DB: postgresql+psycopg2://postgres:***@postgres/airflow
This will drop existing tables if they exist. Proceed? (y/n)y
