feat: upgraded score-go to 1.1.0 and supressed double error printing

[astromechza]

Like the similar PR's submitted to score-compose and others, this PR updates the version of score-go (and thus the embedded score spec). This adds tighter and more useful validation and error messages and ensures that score-helm meets the score spec and expected behavior.

(We also update the version of Go being used).

Demo

When run against the score-full.yaml file from the score schemas repo, we get:

$ go run cmd/score-helm/main.go run -f ../schema/samples/score-full.yaml
containers:
  container-one1:
    args:
      - hello
      - world
    command:
      - /bin/sh
      - -c
    env:
      - name: SOME_VAR
        value: some content here
    image:
      name: localhost:4000/repo/my-image:tag
    livenessProbe:
      path: /livez
      port: 8080
      type: http
    readinessProbe:
      httpHeaders:
        SOME_HEADER: some-value-here
      path: /readyz
      port: 80
      type: http
    resources:
      limits:
        cpu: "0.24"
        memory: 128M
      requests:
        cpu: 1000m
        memory: 10Gi
    volumeMounts:
      - mountPath: /mnt/something
        name: volume-name
        readOnly: false
        subPath: /sub/path
      - mountPath: /mnt/something-else
        name: volume-two
  container-two2:
    image:
      name: .
service:
  ports:
    - name: port-one
      port: 1000
      protocol: TCP
      targetPort: 10000
    - name: port-two2
      port: 8000
  type: ClusterIP

Which is what is expected.
