RDC2019 "Download PDF" links point to non-existent Dropbox files

Links to PDFs of slides from RDC2019 talks now presented on Developer Hub are broken. They point to a Dropbox folder that does not exist, resulting in HTTP 404 error.

On rdcglobal.com, the videos do not have the PDF links, so it’s good to know we have them on Developer Hub, but they need to be working links in order to be helpful.

Perhaps these PDF slides could be hosted on developer.roblox.com directly to avoid depending on a on another external system such as a dropbox folder?

I already posted about this earlier in the Development Discussion category here regarding the RDC websites, however, I wanted to specifically point attention to the broken links on the Developer Hub as well in this separate topic.
