Expected Behavior

What should have happened? each.value should not be reporting an error on inspection. terraform apply works. This makes inspection rules fail incorrectly.

Actual Behavior

What actually happened? Inspection reports error with red text stating "Unresolved reference value"

Steps to Reproduce

Please list the steps required to reproduce the issue, for example:

1. Add for_each to a resource
2. Attempt to use each.value
3. Inspection reports error
4. Terraform apply works.
