required_version is too strict with 0.39.0

[franzs]

Introduction

The new version 0.39.0 of tflint causes extra warnings.

Expected Behavior

No warning should occur as with version 0.38.1 and below.

Actual behavior

Having a terraform block without required_version causes a warning although there is a required_version in another terraform block:

% tflint
1 issue(s) found:

Warning: terraform "required_version" attribute is required (terraform_required_version)

  on  line 0:
   (source code not available)

Reference: https://github.com/terraform-linters/tflint/blob/v0.39.0/docs/rules/terraform_required_version.md

Step to Reproduce

backend.tf:

terraform {
  backend "gcs" {
    bucket = "tfstate"
    prefix = "prefix"
  }
}

versions.tf:

terraform {
  required_version = "~> 1.1.0"
  required_providers {
    google = {
      source  = "hashicorp/google"
      version = "~> 4.27.0"
    }
  }
}

Run tflint version 0.39.0.

Additional Context

% tflint -v
TFLint version 0.39.0
% terraform -v
Terraform v1.1.9
on linux_amd64
