[FIX] website_event_exhibitor: de-traw-ify

Remove t-raw and mark website_description as markup-safe right after
fetching it.

Also update `_fetchSponsor` to use async/await, and remove seemingly
unnecessary empty div in template, and convert `<span>` to `<div>` as
the contents is arbitrary and thus could be a block.
