This is a drop-in adapter layer for vim-plug and lazy.nvim, allowing you to have a core set of vim plugins, configured with Plug, which will also be loaded using lazy.nvim instead whenever you use neovim (alongside any additional set of lazy.nvim plugins you have configured.)
It works by adding a new command Plugin as a drop-in Plug replacement.
That calls a function that sets up lazy.nvim specs for the equivalent Plug
args, and stores them in a variable that you can then add to your lazy spec.
