[wwwdocs] aarch64: Record RNG intrinsics bug fix in 10.3 changes.htm

[Kyrylo Tkachov via Gcc-patches]

Hi all,

I'd like to record the fix for the RNG intrinsics fix in the 10.3 release notes.
The GCC 10 branch is the only released branch that was affected by the bug.

Pushing to wwwdocs.
Thanks,
Kyrill
