Missing required packages in setup/install documentation

Describe the bug
Missing required packages in setup/install documentation

To Reproduce
Steps to reproduce the behavior:

1. Install a "bare metal" RaspberryPi without desktop or other packages.
2. Download PADD
3. Run PADD to connect and display information against a separate PiHole instance.

Expected behavior
PADD should execute and show information

Additional context
Package "jq" is noted as being missing when PADD is first run.
"dig" is then noted as being missing when PADD is next run. This is part of the dnsutils package.

[mwoolweaver]

needs to be added here

PADD/padd.sh

Lines 1467 to 1478 in 47bd6c6

	check_dependencies() {
	# Check for required dependencies
	if ! command -v curl >/dev/null 2>&1; then
	printf "%b" "${check_box_bad} Error!\n 'curl' is missing but required.\n"
	exit 1
	fi
	if ! command -v jq >/dev/null 2>&1; then
	printf "%b" "${check_box_bad} Error!\n 'jq' is missing but required.\n"
	exit 1
	fi
	}

could do something similar to #457

Just needs the install documentation updated with the requirements for jq, dig (dnstools) and curl on a minimal system.
