Description:

We need a configuration option to allow the admin to choose how users initiate workflows within Backstage. Currently, there are two methods:

1. Using the UI form provided by the orchestrator plugin.
2. Creating workflows from Backstage templates and running the workflow by choosing the template.

We will introduce a configuration setting that dictates which of these methods should be the way to initiate workflow runs.

Proposed Configuration Option:

• enableWorkflowsAsTemplates: A boolean value.
  • true: Workflows should primarily be run via Backstage templates. 
  • false: Workflows should run from orchestrator plugin form.

Implementation Details:

• Add the enableWorkflowsAsTemplates option to the plugin's app-config.yaml.
• Modify the run button to navigate to the workflow execution page or to the template page depending on the configuration.
• The default is false, also in case the configuration isn't provided.
