Google Sans Flex font missing in the repo

## Describe the issue
The Google Sans Flex font has been released on Google Fonts and is labeled as OFL licensed.

However, the corresponding font files and descriptions text do not appear to be present in this repository. Given its public release and OFL license, we would expect to find the files here.

Additionally, if the inclusion of the font is intentional, could you consider **releasing the font's source file**?

## To Reproduce
Open [this link](https://fonts.google.com/specimen/Google+Sans+Flex) in your browser.

## Expected behavior
The Google Sans Flex font files should be present in this repository.

## Additional context
The font is missing in this repo.
