zephyr build warnings: zephyr.h is deprecated, include <zephyr/kernel.h> instead

[DhruvaG2000]

Whenever I try to build a sample using latest zephyr, I get a bunch of the following errors:

/home/dhruva/zephyrproject/zephyr/include/zephyr/zephyr.h:13:2: warning: #warning "<zephyr/zephyr.h> is deprecated, include <zephyr/kernel.h> instead" [-Wcpp]
   13 | #warning "<zephyr/zephyr.h> is deprecated, include <zephyr/kernel.h> instead"
