feat(dev): add new developer command for parsing distro details

[MicLieg]

Description

Parse Game Details

• This PR renames command_dev_details.sh to command_dev_parse_game_details.sh to better reflect the purpose of the command.
• Now every variable that info_game.sh can provide will be displayed if set.
• The advantage is that no matter what gameserver is currently installed the command ./gameserver parse-game-details will display every variable that LinuxGSM (info_game.sh) could parse from the games config file.

Parse Distro Details

• This PR adds a new command, similar to command_dev_parse_game_details.sh, which will display every set variable that info_distro.sh can provide (with a few exceptions).

You're absolutley right! I didn't think of that.

I'll submit a PR for the docs in a couple of hours tomorrow 👍

FYI, I'm going to keep the new documentation for this to a minimum for now, and expand it as soon as https://github.com/GameServerManagers/LinuxGSM/pull/4527 and the other two doc PRs are merged.

After that i'm planning to give all the docs some attention and will be refactoring them quite a bit.

This comment was posted to the wrong PR:

For archiving purposes, I'm posting the script I used to extract most of the variables:

#!/bin/bash

# Define the root directory to search in
ROOT_DIR="./lgsm/modules"

# Find all .sh files and process them
find "$ROOT_DIR" -type f -name "*.sh" | while read -r file; do
    echo "File: $file"
    # Extract variables, including those using += for appending
    # Remove duplicates in the same file, ignoring comments
    # and focusing on simple VARIABLE=value or VARIABLE+=value patterns
    # without the value, =, or + character
    grep -Eo '^[[:space:]]*[^#[:space:]]+\+?=[^=]+' "$file" | \
    sed -E 's/\+?=.*//' | \
    sort | uniq | \
    sort | \
    while read -r variable; do
        echo "  - $variable"
    done
    echo # Add a blank line for better readability between files
done
