Zephyr now requires `int main(void)`. Main must return 0, all other
values are reserved.

Zephyr includes are now prefixed with <zephyr/...>. While the old path
can still be used when CONFIG_LEGACY_INCLUDE_PATH=y, it's better to be
prepared for the future.

The initial idea behind this code was to showcase documentation. It does
not add any special value to the sample, so remove it. A proper library
can be added in the future.
