bug: error when variable is in variables.tf file (same for outputs)

[greenkiwi]

I am seeing a bug where the checks are telling me that a variables.tf file should not contain variables and that they should be put in a variables.tf file.

Ensure variables are in `variables[.grouping].tf`........................Failed
- hook id: vars-in-variables-files
- exit code: 1

variables file ok: test/terraform/variables.tf
ERROR: variables.tf MUST not contain variables
Variables defined in files that do not match our naming convention: 'variables[.grouping].tf'
See: https://open-turo.github.io/standards-terraform/modules/input-variables/

Ensure outputs are in `outputs[.grouping].tf`............................Failed
- hook id: outputs-in-outputs-files
- exit code: 1

ERROR: outputs.tf MUST not contain outputs
outputs defined in files that do not match our naming convention: 'outputs[.grouping].tf'
