In the `meta`data for the `google-fonts` package --
- the `homepage` field was set to the URL
<https://www.google.com/fontsl>, which would appear to be a
misspelt version of <https://www.google.com/fonts>, which now
redirects to <https://fonts.google.com>.
- the `description` field referred to Google Fonts as "Google Font".
This patch corrects these errors, and updates the `homepage` URL.
