Add a default i18n setup

[LorisSigrist]

I'm opening this in response to this tweet

Good Internationalisation and Localisation can greatly increase the potential market for a service. If you live / work in a country with multiple languages it may even be a hard requirement. (I live in Switzerland, everything needs 2-4 Languages)

I'm proposing to add a default i18n setup to this template, which would entail:

• Setting up Starlight i18n for the Astro Site
• Setting up i18n for the App
  • Use localStorage to store the language, since SEO isn't as necessary for the App
  • Extracting all hard-coded strings from the App & use an i18n library (may I shamelessy promote ParaglideJs)

I am not proposing to ship the template in multiple languages by default, only to have setup in place to add more languages.

I would be happy to contribute this if you're interested!

This sounds like a great feature. Go ahead and assign yourself @LorisSigrist if you're still willing to take this on 🙏

This is quite interesting. I wonder if it should be a feature at Wasp level at some point. Let's see how this goes, and it might give us some good inspiration for that!
