manifest: update CANopenNode module to v4

Update the CANopenNode module revision in west.yml to track the
v4-based Zephyr integration from zephyrproject-rtos/canopennode#9.

CANopenNode v4 brings a rewritten Object Dictionary interface,
CiA 302/303/304/305/309 support, MISRA C:2012 compliance, and
a complete Zephyr integration layer with Kconfig, storage backends,
LED GPIO bridge, and RT processing thread.
