[Request]: add ownCloud client

[tannenfreund87]

I created a JSON that solves that issue:

{
    "version": "5.2.1.13040",
    "description": "The ownCloud Desktop Client is a tool to synchronize files from ownCloud Server with your computer.",
    "homepage": "https://owncloud.com/",
    "license": "GPL-2.0",
    "suggest": {
        "vcredist": "extras/vcredist2022"
    },
    "architecture": {
        "64bit": {
            "url": "https://download.owncloud.com/desktop/ownCloud/stable/5.2.1.13040/win/ownCloud-5.2.1.13040.x64.msi",
            "hash": "e30eb458dd6e724c69700b881e94e47d0aae7fdbe7292e0e86bb870fb062bc0f"
        }
    },
    "extract_dir": "PFiles\\ownCloud",
    "bin": [
        "owncloudcmd.exe",
        [
            "owncloudcmd.exe",
            "owncloud"
        ]
    ],
    "shortcuts": [
        [
            "owncloud.exe",
            "ownCloud"
        ]
    ],
    "checkver": {
        "url": "https://owncloud.com/de/desktop-app/",
        "regex": "ownCloud-([\\d.]+).x64.msi"
    },
    "autoupdate": {
        "architecture": {
            "64bit": {
                "url": "https://download.owncloud.com/desktop/ownCloud/stable/$version/win/ownCloud-$version.x64.msi"
            }
        }
    }
}

Warning: there is a restriction. Similar to the Nextcloud-client, there is no Windows Explorer shell integration!
