Add Highload++ talk

@johscheuer Could you please help add Highload++ talk by Daniil Gitelson (@theos) to our Awesome FoundationDB list. I just discovered it on YouTube.

Thanks @theos for the interesting talk.

I created a PR: Add HighLoad++ Armenia 2022 talk by johscheuer · Pull Request #22 · FoundationDB/awesome-foundationdb · GitHub thanks for adding this talk!

Cool! Thanks for adding :slight_smile:
