${environment.name} is not interpolated appropriately on deploy action

[KoduIsGreat]

Bug

I have the following Deploy action that sets up some kubernetes secrets that utilizes ${environment.name} to select the correct varfile to merge into the deployment but it does not work. Note previously this worked with Modules Here is an example of the Module that worked before

kind: Module
name: secrets
type: kubernetes
manifests:
  $forEach: ${var.secrets}
  $return:
    apiVersion: v1
    kind: Secret
    metadata:
      name: ${item.key}
    type: Opaque
    stringData:
      $merge: ${item.value}
varfile: secrets.${environment.name}.yaml

Current Behavior

kind: Deploy
name: secrets
type: kubernetes
spec:
  manifests:
    $forEach: ${var.secrets}
    $return:
      apiVersion: v1
      kind: Secret
      metadata:
        name: ${item.key}
      type: Opaque
      stringData:
        $merge: ${item.value}
varfiles: 
  - ./secrets.${environment.name}.yaml

I get the following error when I run garden deploy

Error processing config for Deploy action secrets:
Could not find varfile at path './secrets.${environment.name}.yaml'

If i hard code it to the environment e.g. "local" it works.

Expected behavior

It should interpolate the environment name as part of the filepath

Reproducible example

git clone https://github.com/KoduIsGreat/garden-bug
cd to garden-bug
garden deploy -l5

To add some context, I experienced this issue using the following:

kind: Project
...
variables:
  baseHostName: ${command.params.env}.scalecomputing.dev

This led me to believe it was the --env flag specifically.
