Consider using Github Actions (or equivalent) to keep fonts up-to-date

Hi, thank you all for the project.

The various foundries on Google Fonts add & update their fonts at breakneck speed, & thus the fonts found here tend to get outdated pretty quickly, as mentioned in #94 #89 #80.

Could the maintainers here consider using some sort of CI/CD pipeline to automate the process of pulling in new fonts? Similar work was put into place at @material-design-icons/svg, with their workflow to diff & pull in changes nightly. (As well as maic woo!! 🎉🎉)

Thank you for your consideration in advanced.
