Picolibc module and SDK are not in sync for Zephyr 4.2.0

[stephanosio]

Describe the bug

As per the documentation, for every Zephyr release, the Picolibc module and the corresponding pre-built SDK Picolibc must be in sync:

For every release of Zephyr, the toolchain-bundled Picolibc and the Picolibc module are guaranteed to be in sync when using the recommended version of Zephyr SDK.

This is not the case for the Zephyr 4.2.0 release, which has its west.yml pointing to the Picolibc commit ca8b6ebba5226a75545e57a140443168a26ba664 and the corresponding SDK 0.17.2 release (from SDK_VERSION) pointing to the Picolibc commit c7cc2483d591784bb2707f72b0784d92074f5347.
