Include Plugin as an Object rather than a String

[Just-Hussain]

Is your feature request related to a problem? Please describe.

I've noticed that the only plugin in my nuxt project that get included in the plugins array in a string form rather than as an object is this plugin.
Its a minor issue, maybe even not, but I've found it annoying to check for plugins as objects and strings, in for example extendPlugins.

Describe the solution you'd like to see

Include it as an object

{ src: '~/.nuxt/auth.js' }

Describe alternatives you've considered

My solution was just to check if the item in the plugins array as an object or a string, and proceed on that. This os annoying especially with TypeScript.

Additional context

Here is a screenshot of what i mean, all plugins are object. The only one that is a string is auth.

That's it, great plugin though thanks for the hard work!
