feat(ui_firestore): Expose index to FirestoreItemBuilder

[jt274]

@russellwheatley I'm not sure if this is completed yet, as it didn't appear to make it into the last pub release after you merged.

@russellwheatley Still not released?

Hey @jt274 - you need to either update this PR or create a new one. It wasn't merged with main, I just ran the CI. You need to completely remove anything not related to the exposing the index to FirestoreItemBuilder

@jt274 @russellwheatley, can this task be done already, please!

[jt274]

@russellwheatley branch should be fixed!
