[Chrome 108+][validation] browserHash can have 2 different values for the same browser version

[t2ym]

[Chrome 108+] browserHash can have 2 different values for the same browser version

Root Cause

• With Chrome 108 and later versions, document.prerendering can have one of these 2 values: true and false, which affects the browserHash value

Workaround

• In Validation Service, validate the 2 distinct browserHash values for each browser version

Fix

• Exclude document.prerendering in generating browserHash
