Allow uploading PDFs and other file types (other than images/video)

When writing, I might have documents (google doc, pdf, txt, other) with content I wrote before. It’d be great if I could include / upload those contents as a reference, or even as a way of creating a new article that would be a consolidation of those contents. IRL example: I talked to 20+ experts from a certain industry, researching certain aspects of their experience, and generated a number of documents with my notes and insights from all of those conversations; I’d like to bring all of them to tiptap, so that I can write a number of different articles based on those insights
