Revert "Update Azure Core and Synapse SDK"

Reverts #28764

The PR turns out to have bigger impact than expected. IotHub had a fixed dependency to "Microsoft.Extensions.Logging.Abstractions" which caused conflicts.

Need more time to figure out a solution. (Removing the package reference doesn't block building the module, maybe it's not required?)
