Add WASM Summit (#1018)

Based off of #995 and #623.

The WASM page from last year linked to ticket info but we don't have
that page up yet, correct?

@ntoll : as agreed, I copied the info from last year. Could you please
take a look at this page/the preview and make sure everything looks
alright? 🙏
