feat(options)!: deprecate paste, remove pastetoggle (#22647)

we cannot remove 'paste'. It is very common in plugins and configs.

'pastetoggle' can and should be removed though, it's a total waste of everyone's time because it generates bug reports and doesn't work well, and is useless because bracketed-paste works better.
