Fix project description typo on composer integration of EXIF

In the project description there is the following direction for installing exif-js via composer.
In the DIST value, there is an extra comma ',' in the end of the URL line which causes the error on install.
Please update the project page accordingly.

    {
        "type": "package",
        "package": {
            "name": "exif-js/exif-js",
            "version": "v2.3.0",
            "type": "drupal-library",
            "dist": {
                "type": "zip",
                "url": "https://github.com/exif-js/exif-js/archive/refs/tags/v2.3.0.zip",
            }
        }
    },

should be

    {
        "type": "package",
        "package": {
            "name": "exif-js/exif-js",
            "version": "v2.3.0",
            "type": "drupal-library",
            "dist": {
                "type": "zip",
                "url": "https://github.com/exif-js/exif-js/archive/refs/tags/v2.3.0.zip"
            }
        }
    },
