Document serving static files

[mischnic]

From @subuta in parcel-bundler/parcel#3407 (comment):

Create .proxyrc.js with these contents.

const serveStatic = require('serve-static')

module.exports = function (app) {
  // Use static middleware
  app.use(serveStatic('static'))
}

Then you may access your static file like this http://localhost:1234/test.txt

Took me a while to realize I also needed to npm install serve-static to get the example proxyrc file working.
