nvim: Allow pasting images into markup files

With the new `img-clip.nvim` extension we can copy any image anywhere
and simply paste it into a markdown/quarto/latex/typst/... document with
the right markup already.

Those can be from the web/locally. Also allows drag and drop from e.g.
web pages.

Mapped to `<leader>pp` currently, though we will have to find a better
mapping. Or invoked with `:ImagePaste`.
