[FEATURE]: Return outputs from terraform as json string

[ITHedgeHog]

Feature Request

Background / Motivation

We use Azure CLI to set the secrets based on terraform output - when we put all of these outputs together it is longer than the buffer (9K characters).

We would like to access the entire outputs as a json string.

What should the user be able to do?

access ${actions.deploy..outputs.* as a json string.

Why do they want to do this? What problem does it solve?

I can't use terraform in garden for any members of my team using Windows.

Suggested Implementation(s)

How important is this feature for you/your team?

🥀 Crucial, Garden is unusable for us without it

Hi @ITHedgeHog , this actually already works if you use the jsonEncode template helper function, since outputs is a plain object e.g.: ${jsonEncode(actions.deploy.tf.outputs)} or ${jsonEncode(providers.terraform.outputs)}.
EDIT: It works for provider outputs, but not for action outputs. Reopening.
