Remove QueuedText (#7414)

## Objective

Remove `QueuedText`.

`QueuedText` isn't useful. It's exposed in the `bevy_ui` public interface but can't be used for anything because its `entities` field is private.

## Solution

Remove the `QueuedText` struct and use a `Local<Vec<Entity>` in its place.

## Changelog

* Removed `QueuedText`
