[RFC] syzkaller/docs: reporting kernel security bugs guide

[Sabyrzhan Tasbolatov]

Hello,

Greg,
Could you please confirm that the updated version of
reporting Linux kernel security bugs guide is correct
since kernel.org is CNA as of February 13, 2024 and
with linux-cve-announce reference?

The updated doc and drawn diagram is available
in this PR of syzkaller project:
https://github.com/google/syzkaller/pull/5461

Please also see the diagram in the PR
docs/linux/reporting_kernel_bugs.png.

Thanks
