Incorrect installation snippet for Lazy.nvim

[kjkent]

The plugin code for Lazy.nvim needs to be a return statement :)

return {
    'stevearc/dressing.nvim',
    opts = {},
}

Many thanks to stevearc and all the collaborators!

It only needs to be a return if you put it in a file by itself. I have no idea if you're going to put this in a separate file or include it in a larger list of plugins, so I'm keeping the structure agnostic.
