Add specific source maps docs for Cordova

[lforst]

We want to add more detailed and in-depth source maps docs that are specific to Cordova. Similar to what we do for Remix or Next.js

When tackling this task we should also check the troubleshooting page, whether anything can be improved there too for Cordova.

This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you label it Status: Backlog or Status: In Progress, I will leave it alone ... forever!
