chore: add Yandex to ruleid

[fzipi]

We received a formal request from Yandex to reserve the 8,000,000-8,999,999 id range.

Hi dear collegues!
Hope you are doing well.
 
I'm Ruslan.
So now we are develop ruleset, based on SecLang.
According to documentation, gentle way - to reserve IDs in documentation if we plan to share our rules with extenal customers.
 
It will be great to reserve, for example,
ids: 8,000,000-8,999,999 - > Yandex
