chore: bump postgresql in docker-compose and github workflows

[sebastianliebscher]

SUMMARY

This PR bumps to postgresql:15 image version in Dockerfile and GH workflows.

---

Postgres 15.0 change log: https://www.postgresql.org/docs/release/15.0/

From Postgres release news:

In this latest release, PostgreSQL improves on its in-memory and on-disk sorting algorithms, with benchmarks showing speedups of 25% - 400% based on which data types are sorted. Using row_number(), rank(), dense_rank(), and count() as window functions also have performance benefits in PostgreSQL 15. Queries using SELECT DISTINCT can now be executed in parallel.

---

Note: The Helm Chart already uses PostgreSQL 15 as introduced in #22590. Version >=12 uses postgres 15.X. See https://github.com/bitnami/charts/tree/main/bitnami/postgresql/#to-1200
