Update availability-zones-migration-overview.md

Hi @anaharris-ms , I'm Penny Ko in MSFT. 
I noticed there are a few Azure Services that wasn't being listed in the table even though there's docs in the TOC. 
I've tried my best to add them here.
Please kindly check and review whether the reference links I've added are in the right format. Thank you!
