Setting git global config not working for using PAT token

[Ankit Choudhary]

Describe the bug
After setting git global config to use PAT token for all request on github is not working with terragrunt-action.
Please find below the code snippet:

   - name: Github InsteadOf setup
        run: |
          git config --global url."https://username:${{env.PAT_TOKEN}}@github.com".insteadOf "https://github.com"   
    
    
    - name: Terragrunt Init
      uses: gruntwork-io/terragrunt-action@v1.0.1
      with:         
        tg_version: ${{ env.TERRAGRUNT_VERSION }}
        tf_version: ${{ env.TERRAFORM_VERSION }}
        tg_dir: ${{ env.working-directory }}
        tg_command: "init"

To Reproduce
Steps to reproduce the behavior, code snippets and examples which can be used to reproduce the issue.
Try to use a private repository as source of terraform module using github PAT token
terraform code:

module "app" {
  source          = "github.com/org-name/repo.git//path/to/module?ref=branch"  
}

Github action code:

   - name: Github InsteadOf setup
        run: |
          git config --global url."https://username:${{env.PAT_TOKEN}}@github.com".insteadOf "https://github.com"   
    
    
    - name: Terragrunt Init
      uses: gruntwork-io/terragrunt-action@v1.0.1
      with:         
        tg_version: ${{ env.TERRAGRUNT_VERSION }}
        tf_version: ${{ env.TERRAFORM_VERSION }}
        tg_dir: ${{ env.working-directory }}
        tg_command: "init"

Expected behavior
I should be able to use private github repository as source of terraform modules

Nice to have

• Terminal output:

│ fatal: could not read Username for 'https://github.com/': No such device or address

• Screenshots

Versions

• Terragrunt Action version: 1.0.1
• Environment details (Terragrunt version, Terraform version, etc.): terragrunt-version: 0.48.1, terraform-version: 1.5.2

Hello,
changes performed outside of workspace directory aren't passed to action container, in the current case git config --global ... change contents of /home/runner/.gitconfig

However, since version 1.0.2 can be passed environment variables with scripts which will be executed before running Terragrunt, and can be passed git config --global command

Example:

...
      - name: Plan
        uses: gruntwork-io/terragrunt-action@v1
        env:
            INPUT_PRE_EXEC_1: |
              git config --global url."https://denis256:${{secrets.PAT_TOKEN}}@github.com".insteadOf "https://github.com"
        with:
          tf_version: ${{ env.tf_version }}
          tg_version: ${{ env.tg_version }}
          tg_dir: ${{ env.working_dir }}
          tg_command: 'run-all plan --terragrunt-log-level debug'
...
