[bug\_fix] Image built with docker buildx build does not appear in docker images despite a successful build

Add the --load flag to the docker buildx build command to export the image to the local Docker daemon's image store.

Journey Context:
A developer configures docker buildx to leverage BuildKit features or multi-architecture builds. The build completes successfully with no errors, but when they try to run the image with docker run, it fails with 'Unable to find image' and automatically tries to pull from a registry. They check the Dockerfile and tag syntax, thinking they made a typo. The rabbit hole deepens as they inspect buildx instances and drivers. They eventually realize that the default buildx driver is 'docker-container', which runs the build inside an isolated container. This container has its own image cache, completely separate from the host's local Docker daemon. By adding --load, they instruct buildx to push the built image from the isolated builder container back into the host daemon's image store, making it available for local docker run commands.
