Add terragrunt-providers-lock hook

[Tensho]

Describe the solution you'd like

It would be nice to have a hook which locks versions in .terraform.lock.hcl file automatically. For example, terragrunt-providers-lock hook which runs terragrunt providers lock command for specified platforms under the hood.

Describe alternatives you've considered

Write a local hook, something like:

  - repo: local
    hooks:
      - id: terragrunt-providers-lock
        name: Terragrunt providers lock
        entry: terragrunt providers lock -platform=darwin_amd64 -platform=darwin_arm64 -platform=linux_amd64
        language: script
        files: '\.hcl$'

Additional context

A similar terraform_providers_lock hook for Terraform is provided by pre-commit-terraform project.
