support full terraform plan output

As a consumer of these actions, I need a detailed plan output including a detailed view of changes. Today I only have a summary view using the outputs of the standard actions.

I need this data to be able to understand what is, created, changed or destroyed beyond a count, this is a critical part of the review process.

As an example to understand what changes are in a plan, I can review the structured plan output in the TFC UI, whilst it's possible to provide a link to the plan detail in the UI for review this breaks the review process flow. It would be preferable to have the JSON data of this view so I can format and summarize in a PR comment
