docs: adapt to new lazy.nvim best practices for dependencies

If your plugin needs setup(), then create a simple lazy.lua file like this:

return { "me/my-plugin", opts = {} }

Plugins that are pure lua libraries should be lazy-loaded with lazy = true.

{ "nvim-lua/plenary.nvim", lazy = true }

Only use dependencies if a plugin needs the dep to be installed AND loaded. Lua plugins/libraries are automatically loaded when they are require()d, so they don't need to be in dependencies.
