Update Google Fonts to include Google Sans Flex, and other new fonts

I design on a Chromebook and I’m unable to use the Figma font helper. I really want to use the Google Sans Flex font which was recently released, alongside other new fonts like Stack Sans, and the TASA typeface collection. I don’t have access to a regular computer to use them. The Inter font is also outdated and it doesn't have the option to adjust optical size.
