Version number of external dependencies should be specify at the right place

[kelson42]

For the moment, we have:

base_deps_versions = {
    "zlib": "1.3.1",
    "lzma": "5.2.6",
    "zstd": "1.5.2",
    "docoptcpp": "0.6.2",
    "uuid": "1.43.4",
    "xapian-core": "1.4.26",
    "mustache": "4.1",
    "pugixml": "1.15",
    "libmicrohttpd": "0.9.76",
    "gumbo": "0.13.1",
    "icu4c": "73.2",
    "libaria2": "1.37.0",
    "libmagic": "5.44",
    "android-ndk": "r21e",
    "org.kde": "6.9",
    "io.qt.qtwebengine": "6.9",
    "zim-testing-suite": "0.8.0",
    "emsdk": "3.1.41",
}

in kiwixbuild/versions.py

This number should be put as a property of the class Dependency.
