Added Arma 3 image files

These files originate from https://github.com/parkervcp/images/tree/game/arma3 which is currently hosted at quay.io/parkervcp/pterodactyl-images:game_arma3
However, the entire image has been mainly rewritten in this update, which includes the following changes:
- Code styling / nomenclature has been normalized across the entire file.
- A robust RunSteamCMD function has been added to run SteamCMD with advanced error handling and reporting. Works for both the server and mods, and is configurable with the STEAMCMD_ATTEMPTS environment variable to specify how many times it should retry a download after a recoverable error (like large Workshop mod downloads timing out).
- Added support for a MOD_FILE environment variable, to specify an exported Arma 3 modlist HTML file for import into the server (for downloads and runtime). These mods are combined with any mods listed in MODIFICATIONS.
- A more robust and automatic way of downloading/updating mods is now included with the UPDATE_SERVER function. All mods to be used during runtime are checked for updates by comparing local file's creation dates against the mod's Workshop page last update. This allows for fast and reliable mod updates compared to the old manual system, and allows users to comfortably leave the update server function on all the time if they'd like.
- Added a RemoveDuplicates function to prevent a user from accidentally loading a mod twice.
- Checks for missing, trailing semicolons in manual mod lists due to human error.
- Mod update information echos are less cryptic and now use the mod's human-readable name, as well as printing the date they last updated.
- Made the server binary check error messages less cryptic and provided solution recommendations.
- Added a CLEAR_CACHE env. var. function to delete headless client profiles on startup to help with potential issues they cause.
- Un-hardcoded the basic.cfg URL and replaced with env. var.
- Added HC_HIDE env. var. to prevent headless client console spam.
- Added VALIDATE_SERVER env. var. to manually validate, because the new automatic update function skips validation to speed it up.
- Added CDLC env. var. for easy download of Creator DLCs incase the user doesn't know how to use SteamCMD beta branches.
