Push Multi-Architecture Docker Images with BuildX

Docker Buildx is a plugin for the Docker CLI that extends the core docker build command with advanced features powered by Moby BuildKit. You can use BuildX to easily build and push multi-architecture images with a single command.

To build and push multi-architecture images with BuildX:

Run this command to open a new builder instance that you can use to build images for multiple architectures:
```
docker buildx create --use
```
Build and publish multiple images by running the following command:
```
docker buildx build --platform <ARCHITECTURES> -t [JFrogPlatformURL]/<REPO_NAME>/<IMAGE>:<TAG> . --push
```
Where:
- <ARCHITECTURES>: A comma-separated list of the operating system and CPU combinations you want to build
- [JFrogPlatformURL]: The URL of your JPD, without the protocol schema
- <REPO_NAME>: The repository where the image is located
- <IMAGE>: The image name
- <TAG>: The tags identifying the version of the image you want to pull
For example:
```
docker buildx build --platform linux/amd64,linux/arm64,linux/arm/v7,linux/s390x,linux/ppc64le -t company.jfrog.io/docker-local/froggy-app:v1.0.0 . --push
```
