Add python compatibility check function to ./scripts/setup.sh

[JH-LEE-KR]

On Ubuntu, the default Python version varies by release:

• Ubuntu 18.04 LTS: Python 2.7
• Ubuntu 20.04 LTS: Python 3.8
• Ubuntu 22.04 LTS: Python 3.10

Currently, the Ansible installation process in ./scripts/setup.sh proceeds without verifying the compatibility of the Python version on the system.
This can result in installation failures that may be difficult for users to determine the cause of.

I propose enhancing the setup process to first check the compatibility between the Ansible version and the Python version.
This pre-check will help users understand potential incompatibilities upfront and prevent confusing installation errors.

Pull Request Overview

Adds a pre-check in setup.sh to verify that the system’s Python version satisfies the Python requirement declared by the targeted Ansible release.

• Introduces jq to platform-specific dependency lists
• Fetches Ansible metadata from PyPI and extracts requires_python
• Implements a Bash function to parse and enforce version constraints

• [nitpick] This new compatibility-check logic isn’t covered by any automated tests; adding unit or integration tests for common version scenarios will help prevent regressions.

The constraint parsing removes commas instead of splitting on them, so multi-part requirements like ">=2.7,<4.0" become a single token. Replace sed 's/,//g' with sed 's/,/ /g' to iterate over each requirement separately.

Suggested change

	for c in $(sed 's/,//g' <<< "$1"); do
	for c in $(sed 's/,/ /g' <<< "$1"); do

[nitpick] Relying on response content to detect a missing package can be brittle. Consider checking the HTTP status code (e.g., with wget --server-response or using curl -s -o /dev/null -w '%{http_code}') before parsing the body.

Suggested change

	JSON=$(wget -qO- "https://pypi.org/pypi/ansible/$ANSIBLE_VERSION/json")
	[[ -z "$JSON" || "$JSON" == *"Not Found"* ]] && { echo "Not found: Ansible $ANSIBLE_VERSION"; exit 1; }
	HTTP_STATUS=$(wget --server-response -qO- "https://pypi.org/pypi/ansible/$ANSIBLE_VERSION/json" 2>&1 | awk '/^ HTTP/{print $2}' | tail -n1)
	if [[ "$HTTP_STATUS" != "200" ]]; then
	echo "Not found: Ansible $ANSIBLE_VERSION (HTTP status: $HTTP_STATUS)"
	exit 1
	fi
	JSON=$(wget -qO- "https://pypi.org/pypi/ansible/$ANSIBLE_VERSION/json")
