message: Fix up the Azure Core changelog for breaking change and new line
diff: ### Breaking Changes
  -- `azure/core/azure_assert.hpp` header is moved to internal. `AzureNoReturnPath()` function is removed from global namespace. Associated macros, such as `AZURE_ASSERT` are renamed to indicate that they are internal. If your code was using the `AZURE_ASSERT` macro, consider using the standard library's `assert` as an alternative.
  +- Removed the `AzureNoReturnPath()` function from the global namespace, and deprecated the associated macros, such as `AZURE_ASSERT` since they are meant for internal use only. If your code was using the `AZURE_ASSERT` macro, consider using the standard library's `assert` as an alternative.
  ### Bugs Fixed
  - Fixed `Azure::DateTime::Parse()` validation if the result is going to exceed `9999-12-31T23:59:59.9999999` due to time zone, leap second, or fractional digits rounding up adjustments.

  - [[#3224]](https://github.com/Azure/azure-sdk-for-cpp/issues/3224) Fixed intermittent crash on macOS when logging is turned on.
