Set user id and Moodle version number manually

If for some reason as in Issue #105 the call to core_webservice_get_site_info fails, the user id and version of Moodle can be manually entered into the configuration.

An entry in config.json may look like the following:

    "userid": 49408,
    "version": 2021051701,

Find the user id: You can find your user id on the profile page of Moodle. For example, 49408 is the user id if the URL of your profile looks like this: https://good.moodle.it/user/profile.php?id=49408.

Find out the Moodle version number: Visit the changelog page of your Moodle https://your.moodle.com/lib/upgrade.txt and see which version number is listed at the top. Then search for this version on the following page (Use [Ctrl + F]): https://docs.moodle.org/dev/Releases and enter the number from the third column into the configuration.
