Feature Request - make Library data class stable

[Nailik]

Stable is used in compose to improve recomposition because objects that didn't change don't need to call a recomposition of the composable where they are shown.

This could either achieved by marking generated Library stable with:

@Stable
Library

or by really making it stable:

• use ImmutableList instead of List
• use ImmutableSet instead of Set

I prefer making both, really making it stable and also add @stable to make it sure. Same for Organization and Developer
