Matrix stats as image on `try.element.io/resilient-communications-study` don't look good at any size

The stats above the "Download study" section are a single image which doesn't display very well (blurry) even at the full page width (non-retina display). But then also get so unreadable and small as you move to mobile widths.

Page: https://try.element.io/resilient-communications-study

> - 200M+ people using Matrix-based communications globally
> - 25+ governments with deployed Matrix-based sovereign systems
> - 40+ competitive vendors in the Matrix ecosystem

Full width (still blurry) | Mobile width (too small to read)

It looks like a text version already exists on https://element.io/en/interoperable-digital-sovereignty which looks a lot better

Start at the resilient-communications-study page and compare its image-based stats above the “Download study” section with the text version on the interoperable-digital-sovereignty page. Replace or adapt the stats presentation so it remains sharp and readable at full-width and mobile sizes, then verify both responsive layouts in a browser.
