[CLOUDGA-12309] Populate providerCode in regions/az even when config …

…is null

Summary:
[CLOUDGA-12309] Populate providerCode in regions/az in case config is null.
YBM as part of edit provider call removes `config` from the GET request. Because of which we are not setting `providerCode` in regions/azs to support backward compatiblity.
This diff removes that check & set `providerCode` for the new regions/zones added.

Test Plan: Manually verified the payload YBM passes.
