Subject: [PATCH] Rename push children to add children (#15196)

# Objective

- Makes naming between add_child and add_children more consistent
- Fixes #15101

## Solution

renamed push_children to add_children

## Testing

- Did you test these changes? If so, how?
Ran tests + grep search for any instance of `push_child`

- Are there any parts that need more testing?

- How can other people (reviewers) test your changes? Is there anything
specific they need to know?

- If relevant, what platforms did you test these changes on, and are
there any important ones you can't test?
ran tests on WSL2

---

## Migration Guide

> This section is optional. If there are no breaking changes, you can
delete this section.

- If this PR is a breaking change (relative to the last release of
Bevy), describe how a user might need to migrate their code to support
these changes

rename any use of `push_children()` to the updated `add_children()`
