Support general files to be uploaded as asset

So far Logseq seems only support media files and pdf as asset, other files couldn’t be uploaded through drag and drop or /Upload an asset command. It would be nice if this could expand to any files, just leave them as links when Logseq itself does not support them.

Yes! I found out that you can’t import .excalidraw files and I expected it to work out of the box! I had to manually “link” them.
