#### Why I did it
The docker tag needed to be updated to use the correct version when SONIC_CONFIG_USE_NATIVE_DOCKERD_FOR_BUILD is set to true.
Today, it always assume that $name_repo:latest was built, which is not true when SONIC_CONFIG_USE_NATIVE_DOCKERD_FOR_BUILD is set to true, causing build failures as seen in: sonic-net/sonic-buildimage#22735

##### Work item tracking
- Microsoft ADO **(number only)**:

#### How I did it
Updated the relevant configuration in the build system so that the docker tag reflects the correct version when the native dockerd build flag is active.

#### How to verify it

1. Run a build with SONIC_CONFIG_USE_NATIVE_DOCKERD_FOR_BUILD set to true.
2. Check that the docker tag used matches the intended version.
3. Ensure the build completes successfully without docker versioning issues.
