Follow up to #5722 - Wrong ads server url for ads/confirmations development environment

[btlechowski]

Follow up to #5722. The url used for ads development environment is wrong.

Steps to Reproduce

1. Run Brave with flags --enable-logging=stderr --vmodule=brave_ads=3 --brave-ads-development --rewards=development=true
2. Enable rewards
3. Check logs

Actual result:

ads urls points to ads-serve.brave.software.com server
ads grant is shown by default

Was unable to claim the grant

ads catalog was not downloaded, because it points to dummy https://ads-serve.brave.software.com/v1/catalog

Expected result:

ads urls points to ads-serve.brave.software server
rewards and ads work as expected

Note: expected ads url was provided by @tmancey
