Add psql and pgcli to ov tooling

[AetherUnbound]

Description

We recently encountered a case where it would be useful to have psql and pgcli available in the ov environment for interacting with the stack. It seems like the perfect candidate to add to the list of tooling available in ov!

We'll need to touch the following places for this:

1. Adding whatever's necessary to install for the psql utility and pipx to the Docker image

openverse/docker/dev_env/Dockerfile

Lines 49 to 58 in e6259b4

	&& dnf -y install \
	git \
	g++ \
	just \
	jq \
	which \
	nodejs npm \
	python3.12 pipx \
	docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin \
	unzip \

2. Adding psql (or the dependency involved) to the list of dependency explanations

openverse/docker/dev_env/Dockerfile

Line 27 in e6259b4

# Dependency explanations:

3. Adding pgcli to the list of pipx dependencies:

openverse/docker/dev_env/Dockerfile

Line 38 in e6259b4

# pipx dependencies:

4. Adding documentation for it to the included tools

openverse/documentation/general/general_setup.md

Lines 111 to 115 in 90f87b8

	### Included tools
	The containerised `ov` environment includes some excellent general purpose tools
	to interact with Openverse's development environment. Here are some important
	ones you might see used throughout the documentation:

Additional context

Initially came up here: #4610 (review)

Would pgcli be a better alternative? It might also be easier to install via pipx.

Yea that works! We'll still need to have the libraries required for psql, per the install documentation:

Pgcli uses psycopg to talk to postgres database. In order to install psycopg, you will need libpq and python-dev installed on your system. Since psycopg is a C extension for Python, a C compiler is needed to install it on your system.
