feat: support multi-step deployment hooks in project config schema

[Soner (shyim)]

What

Update the .shopware-project.yml config schema so deployment hooks (pre, post, pre-install, post-install, pre-update, post-update) accept both the existing single-script form and the new multi-step form.

Why

The deployment-helper now allows a hook to be defined as a list of titled steps that are executed individually, for clearer per-step output. This PR keeps shopware-cli's schema and config parsing in sync so the new form validates in editors and doesn't break ReadConfig.

Companion to shopware/deployment-helper#89.

Supported forms

deployment:
  hooks:
    # old: single script (unchanged)
    pre: |
      echo "Before deployment"

    # new: list of titled steps
    post:
      - title: Warm up the cache
        script: |
          bin/console cache:warmup
      - title: Notify the team
        script: ./notify.sh

    # new: shorthand list of script strings (untitled steps)
    pre-update:
      - echo "first"
      - echo "second"

How

• New ConfigDeploymentHook / ConfigDeploymentHookStep types in internal/shop/config.go.
  • UnmarshalYAML accepts a string, a list of {title, script} objects, or a shorthand list of script strings; errors on anything else. This matters because ReadConfig unmarshals the project config, so a plain string field would fail on the new list form.
  • JSONSchema() emits oneOf: [string, array<oneOf: [string, {title, script}]>], mirroring the existing custom-schema pattern used by ConfigDeploymentOverrides.
• Regenerated internal/shop/config_schema.json via scripts/schema.go.

Backwards compatibility

Fully backwards compatible — string hooks parse and validate exactly as before.

Testing

• New internal/shop/config_hook_test.go covers string, empty string, step list, string-list shorthand, and the invalid case.
• go test ./internal/shop/, go vet, and gofmt all clean. Schema regeneration is stable.
