External Libraries: Update some external libraries.

This updates three external libraries to their latest versions:

- `backbone` from `1.4.0` to `1.4.1`.
- `underscore` from `1.13.1` to `1.13.2`.
- `clipboard` from `2.0.8` to `2.0.10`.

These are all minor updates containing bug fixes and documentation improvements.

See #55547.
