[FR] UI improvements on the File block

[annieappflowy]

Description

I have just embedded files into a page. Once “upload” and once “embed link”. Since I need an internet connection for documents whose internet link I have embedded, I would suggest that different icons (upload or link) are also used. At the moment it is the same icon (see screenshot). The icon would then be the indicator.

Alternatively, we can add some visual hint rather than different icons:

Impact

The goal here is to give some visual hint for people to tell whether it's an uploaded file or an embed link
