Upgrade to Postgres 14 (locally and in OS)

[raarielgrace]

Describe the task
Upgrade our postgres version from 12 to 14.

Purpose
Migrating from Django 4.2 to 5.2 requires Postgres 14.

Acceptance Criteria

• Postgres 14 is used in the docker compose file for local envs
• The postgres image in the gwells tools project is updated to postgres 14
• All gwells environments use this image
• Confirm backups are running, especially when taking to Dev, Test & Prod
• Document for next version upgrade

Additional context

• Upgrade one version at a time
• Start locally first
• There's likely a migration doc from other people doing this a lot
• Django version timeline: https://www.djangoproject.com/download/
• The postgres image can be viewed by going to 26e83e-tools, selecting the Administrator view, and going to Builds -> ImageStreams -> crunchy-postgres-gis

I forgot this was crunchydb I recall that this might complicate things. It's worth reaching out to someone with crunchy experience to confirm. It may end up not.

Looks like we can use pg_upgrade. To avoid having to do the manual backup steps: dump/restore.
