Allow .rmd and .qmd files

[CharlesNepote]

I have a knowledge base with markdown files and Rmarkdown (.rmd) or Quarto (.qmd) files. But it's impossible to open .rmd and .qmd files (web and Android app). I have to use another software.

I would simply love to be able to view and edit thoses files in Nextcloud Notes (both on web and Android app).
