fix: handle index page

[arnauddrain]

The /* redirection will not overrides the default redirection of the / route to index.html, which will not be pre-rendered because.
This can be verified by cloning this repository and deploying it on Netlify, I made a test here: https://astounding-druid-97c6ce.netlify.app
Going to the home page with javascript disabled will just return a blank page, because index.html will be serve, which doesn't include any content.
I'm using the force = true because "/" route redirects by default to index.html which exists in dist/{projectName}/browser

A workaround is to add this redirection to the netlify.toml file of the project using this plugin:

[[plugins]]
  package = "@netlify/plugin-angular-universal"

[[redirects]]
  from = "/"
  to = "/.netlify/functions/angular-builder"
  force = true
  status = 200
