Rename BreakLineOn to LineBreak (#15583)

# Objective

- Improve code quality in preparation for
https://github.com/bevyengine/bevy/discussions/15014

## Solution

- Rename BreakLineOn to LineBreak.

## Migration Guide

`BreakLineOn` was renamed to `LineBreak`, and paramters named
`linebreak_behavior` were renamed to `linebreak`.
