From T369687: Develop a reusable Metrics Platform schema fragment for translation workflows

We have a new

• schema fragment: /fragment/analytics/product_metrics/translation/1.0.0
• and a schema that uses it: /analytics/product_metrics/web/translation/1.0.0

Some of this data is being captured using the action_context field of MP web base schema. The task is to update both the schemas and map the fields necessary to be captured.

• MinT for Readers
• Translation extension
