Auto update Google Fonts library

[mauryaratan]

Currently we manually update the Google Fonts list with each release via a Gulp task. While this was a good idea initially to not wait for Elementor to update the font list, it still opposes the same issue as originally, that is, waiting for the plugin update.

Proposal

Introduce a way to auto-update the Google webfonts list. Maybe a cron task, scheduled to run every 24 hours.

Implementation

• Add a setting to input the Google font API key, with instructions on how to get one.
• If key is added, add a cron event to run every 24 hours to fetch the font list.
• Save the font list to an options object via Options
• Hook it up on https://github.com/analogwp/analogwp-templates/blob/c05c7570cbd3020fd7f9e7e3ab0782721f3e30c9/inc/class-elementor.php#L61
• When saving the list to option, ensure only fonts not present already in Elementor are added. To see how it can be achieved, see https://github.com/analogwp/analogwp-templates/blob/c05c7570cbd3020fd7f9e7e3ab0782721f3e30c9/fonts-massager.php#L31-L36

Additionally, we can pass fields parameter as follows to only include what we need in the response object, otherwise, the object gets pretty huge.

@gvgvgvijayan On second thought, we can make this less painful for customers.
