Include Documentation markdown in releases

[thestonefox]

The release build process currently doesn't build the new documentation folder into the release.

Also, the Documentation folders and all markdown files will need Unity .meta files.

Create a Unity Project with Malimbe as an asset, Unity will create the .meta files for commit.

Also, update the package.json in Malimbe to include the Documentation directory

Malimbe/package.json

Lines 25 to 33 in 9cf1ed0

	"files": [
	"*.md",
	"*.meta",
	"Editor",
	"Runtime"
	],
	"scripts": {
	"prepack": "cp -rf Sources/UnityPackaging/bin/Release/* ."
	}

"files": [
        "*.md",
        "*.meta",
        "Editor",
        "Runtime",
        "Documentation"
    ],

Does "Documentation" need to look back in the parent directory? "../Documentation"?
