Add support for other archive formats like `.tar` instead of just `.zip`

[greenpixels]

I was trying to setup a new project with GodotSteam and GodotEnv, but GodotSteam ships its addon via a .tar.xz archive.

"godotsteam": {
      "url": "https://codeberg.org/godotsteam/godotsteam/releases/download/v4.16.2-gde/godotsteam-4.16.2-gdextension-plugin-4.4.tar.xz",
      "source": "zip",
      "subfolder": "/"
}

This will result in

An unknown error was encountered while attempting to install addons.

System.InvalidOperationException: Failed to run `unzip` in `/home/user/projects/godot/project/.addons/godotsteam` with args `-l /home/user/projects/godot/project/.addons/godotsteam/A53BAC3FF701332D78856357EF1ADE14.zip`. Received exit code 9.

GodotEnv currently only supports .zip files and it could be a good addition to universally support more archive formats.
Maybe using SharpCompress could be a way to go about this.
