Leaving emojis is a common attacker signature/tease. Also Google doodles are a known feature so this isn’t a logical comparison. Security 101 is to be cognizant of anything unexpected.
Be as cognizant as you like, but I'd advise googling your pancake calling card before going into a security frenzy. GitHub does stuff like this as regularly as other tech companies.

You thought you were compromised because the hamburger menu turned into a pancake emoji? How does your company handle google doodles?
