Bump built-in example sketches version to 1.10.0

The Arduino IDE installation includes a collection of example sketches demonstrating fundamental concepts.

These examples are hosted in a dedicated repository, which is a dependency of this project. A new release has been made
in that `arduino/arduino-examples` repository.

This release updates the formatting of the examples to be compliant with the code style of the Arduino IDE 2.x
"Auto Format" feature.
