[PATCH 4/4] scripts: sphinx-pre-install: Integrate interactive mode

[Sai Vishnu M <saivishnu725@gmail.com>]

From: Sai Vishnu M <saivishnu725@gmail.com>

Replace direct printf calls with run_if_interactive for installation
commands across all distro-specific hint subroutines, enabling user
prompts in interactive mode.

Patch series history:
1 -> implement the --interactive flag
2 -> add run_if_interactive subroutine
3 -> add fallback to unrecognized distributions

Testing:
========

Tested: Debian, Ubuntu, Fedora, openSUSE Tumbleweed, Mageia.
Skipped: Gentoo (setup complexity but similarity in modification to others)
Steps taken:
1. Podman to download the containers:
	podman pull docker.io/debian:bookworm
	podman pull docker.io/ubuntu:24.04
	podman pull docker.io/fedora:40
	podman pull docker.io/opensuse/tumbleweed:latest
	podman pull docker.io/mageia:9
	podman pull docker.io/gentoo/stage3:latest

2. Copy the script and related files to a temporary folder
	mkdir -p /tmp/sphinx-test/Documentation/
	cp ./scripts/sphinx-pre-install /tmp/sphinx-test
	cp ./Documentation/conf.py /tmp/sphinx-test/Documentation
	cd /tmp/sphinx-test

3. Connect to the containers
	podman run -it --rm -v $(pwd):/work:z CONTAINER:VERSION bash
	Ex: podman run -it --rm -v $(pwd):/work:z debian:bookworm bash
	
4. Install perl and dependencies
	# Debian/Ubuntu
	apt-get update && apt-get install -y perl sudo
	# Fedora
	dnf install -y perl sudo
	# OpenSUSE
	zypper install -y perl sudo
	# Mageia
	dnf install -y perl sudo
	# Gentoo (requires more setup)
	emerge-webrsync && emerge dev-lang/perl

5. Run the script
	a. Interactive
		cd /work; perl sphinx-pre-install --interactive
	b. Non Interactive
		cd /work; perl sphinx-pre-install
