Flavor validation on package create

[decleaver]

Is your feature request related to a problem? Please describe.

If you attempt to create a package with a flavor that doesn't exist, as long as there is a component you don't get an error or warning about passing in a bad flavor.

Example: (I know this one is silly) but if you do zarf package create <dir> --flavor patchVersion9 it doesn't let you know you specified a bad flavor since you still have the podinfo component, but neither of the podinfo-flavor components get added to the created package.

zarf.yaml

kind: ZarfPackageConfig
metadata:
  name: podinfo
  version: 0.0.1

components:
  - name: podinfo
    required: true
    charts:
      - name: podinfo
        version: 6.4.0
        namespace: podinfo
        url: https://github.com/stefanprodan/podinfo.git
        gitPath: charts/podinfo
    images:
      - ghcr.io/stefanprodan/podinfo:6.4.0
    actions:
      onDeploy:
        after:
          - wait:
              cluster:
                kind: deployment
                name: podinfo
                namespace: podinfo
                condition: available

  - name: podinfo-flavor
    required: true
    only:
      flavor: patchVersion2
    charts:
      - name: podinfo
        version: 6.6.2
        namespace: podinfo-flavor
        url: https://github.com/stefanprodan/podinfo.git
        gitPath: charts/podinfo
    images:
      - ghcr.io/stefanprodan/podinfo:6.6.2
    actions:
      onDeploy:
        after:
          - wait:
              cluster:
                kind: deployment
                name: podinfo
                namespace: podinfo-flavor
                condition: available

  - name: podinfo-flavor
    required: true
    only:
      flavor: patchVersion3
    charts:
      - name: podinfo
        version: 6.6.3
        namespace: podinfo-flavor
        url: https://github.com/stefanprodan/podinfo.git
        gitPath: charts/podinfo
    images:
      - ghcr.io/stefanprodan/podinfo:6.6.3
    actions:
      onDeploy:
        after:
          - wait:
              cluster:
                kind: deployment
                name: podinfo
                namespace: podinfo-flavor
                condition: available

Describe the solution you'd like

• Given a zarf.yaml with components using flavors
• When running zarf package create <dir> --flavor with an invalid flavor
• Then I get a messaging saying something like "Learn how to spell buddy!" or "invalid flavor specified"

Great issue, We are adding on create validation in #2585 and will make sure this gets in as a validation error.
