refactor: remove optimizeDeps.plugins

BREAKING CHANGE: `optimizeDeps.plugins` has been removed. The dep
optimizer is now using `esbuild`, and all non-js files are automatically
externalized to be processed by Vite's transform pipeline when imported.

-  By default, Vite assumes dependencies ship plain JavaScript and will not attempt to transform non-js file formats during pre-bundling. If you wish to support special file types, e.g. `.vue` files, you will need to supply the relevant plugins via this option.
+  A list of packages to be treated as "linked". Linked packages will not be pre-bundled - Vite will analyze and pre-bundle its depndencies instead.
 
-  Note that you will also need to include these plugins in the main `plugins` option in order to support the same file types during production build.
+  Note that if you are using a monorepo via package manager workspaces, and have the packages listed as dependencies in your Vite entry package, Vite will automatically treat them as linked (by checking if it's inside `node_modules`). This option is only needed if you have unusual setups where your Vite app is importing from a package that isn't already linked as a Node-resolvable dependency.
