More developer-friendly Ember builds

[a13o]

The Ember TodoMVC app is currently minified, with sourcemaps disabled. This makes it difficult to browse the code from the todomvc website using devtools.

I would like to modify the Ember build config so that it doesn't minify and it contains sourcemaps.

This is in the spirit of the README:

We intentionally use the unminified versions to make reading the source code easier.

Hello @a13o,

Thanks for highlighting this and your willingness to contribute, we appreciate it a lot. It's also worth noting that our Ember app was initialized with an older CLI version and hasn't incorporated the latest todomvc-app-css. Your assistance in updating this would be greatly valued.

On a related note, there were attempts to address similar concerns at #2140 and #2103. However, they remain unmerged due to a period of inactivity on this project. I recommend connecting with those contributors; their work might offer a starting point for your efforts. I am also here in case you need any assistance or support to get this completed and merged.

Started a PR here: #2209
I'll take it out of draft when I think it's in a good spot, I'm still upgrading stuff atm, but just wanted to leave a link trail)
