Describe the bug
Failed when trying to redirect tg command to file

To Reproduce
When try to redirect tg_command output to a file

    - name: Run Terragrunt Plan Json output
      if: ${{ inputs.ACTION == 'plan' }}    
      uses: gruntwork-io/[email protected]
      with:
        tf_version: ${{ env.TERRAFORM_VERSION }}
        tg_version: ${{ env.TERRAGRUNT_VERSION }}
        tg_dir: vars/${{ env.ENVIRONMENT }}
        tg_command: 'show -json  output.tfplan > tfplan.json'

    - name: Run Terragrunt Plan txt output 
      if: ${{ inputs.ACTION == 'plan' }}    
      uses: gruntwork-io/[email protected]
      with:
        tf_version: ${{ env.TERRAFORM_VERSION }}
        tg_version: ${{ env.TERRAGRUNT_VERSION }}
        tg_dir: vars/${{ env.ENVIRONMENT }}
        tg_command: 'show --no-color  output.tfplan  2>&1 > tfplan.txt'

Expected behavior
Should be able to redirect to a file. Can do it locally.

Nice to have

• Terminal output
  

Versions

• Terragrunt Action version: v1.0.10
• Environment details (Terragrunt version, Terraform version, etc.): TERRAFORM_VERSION: 1.6.5
  TERRAGRUNT_VERSION: 0.53.8

This error may happen because the command is already redirected to a temporary file in the action (check https://github.com/gruntwork-io/terragrunt-action/blob/b055fa001b7487f9f524596777182af5f9bf712b/src/main.sh#L61C38-L61C65)

What could be done eventually is to add an optional input to the action, for the user to inform this temporary file name to gather this specific command output, for the user to manipulate in later steps.
