multiplatform build should fail when base image not available for a specified platform

[anuraaga]

Environment:

• Jib version: 3.2.0
• Build tool: Gradle
• OS: Linux

Description of the issue:

Build silently ignores platforms that have been defined but the base image doesn't support.

Expected behavior:

Build should fail when a platform isn't available. docker buildx does so, i.e.
error: failed to solve: amazoncorretto:17-alpine-jdk: no match for platform in manifest sha256:07d678945d7c61706739add66331f7bd4bd5e290aa6e0c7cbefc9379ac86b225: not found

Steps to reproduce:

1. ./gradlew jib with configuration like below

jib-gradle-plugin Configuration:

jib {
  to {
    image = "someimage"
  }
  from {
    // Any image that doesn't support arm64
    image = "amazoncorretto:17-alpine-jdk"
    platforms {
      platform {
        architecture = "amd64"
        os = "linux"
      }
      platform {
        architecture = "arm64"
        os = "linux"
      }
    }
  }
}

In our project, we added the platforms block expecting arm64 but found it to only support amd64

docker manifest inspect -v public.ecr.aws/aws-otel-test/aws-otel-java-spark:66141a5e34a68c1954f535ac5105457514917d5a

After some thunking, finally realized that the base image also needed to be updated for arm64

After adding to our base image

aws-observability/aws-otel-java-instrumentation@891a9f6

the image now has arm64 support as well

docker manifest inspect -v public.ecr.aws/aws-otel-test/aws-otel-java-spark:891a9f603414b0d02028ee21a4ce392015f352c8

Failing fast, like buildx, will make it easier / quicker to find such an issue.
