nvim: Remove criticmarkup

Sad but I'll have to face it - I've never successfully used
criticmarkup in, by now, 6 years of professional academic writing.

The plugin also does not work as well as it should (anymore?) with my
current neovim setup. The `:Critic` command works neither with accept
nor reject and the different highlights are presumably overwritten by
treesitter queries.

Now, all of those _could_ be fixed but as I say above, I have never
successfully used the markup. Perhaps one day it could be implemented in
a slick nvim lua plugin with hiding and extmarks which mimicks a truly
nice review editing experience. But not today.
