feat: WebIndexPlugin now accepts a template as a string literal

[Shepless]

As requested by @pyros2097 in #885 . Its a simple enough change so I did it real quick. Allows you to do the following:

plugins: [
   WebIndexPlugin({
      templateString: `Your stuff here`
   })
]

NOTE: If you specify a templateString and template then template will take precedent

Nice. So fast that too while polybar was still compiling on my system. On first I thought you were some old man with beard but on closer look that looks a lot like soap.
I suggest you use lemon bar for your beards from now on.
