Not compatible with modern terragrunt versions after CLI redesign

[languitar]

Terragrunt has removed the terragrunt prefix for many CLI options recently. However, the digger code hard-codes a few terragrunt options using the old conventions. This makes digger apply fail with modern terragrunt versions:

time=2025-10-06T13:32:34.235Z level=INFO msg="Running Terragrunt command" command.binary=terragrunt command.args="[apply -lock-timeout=3m --auto-approve --terragrunt-non-interactive]" command.workingDir=/home/runner/xxxx

Error: Failed to parse command-line flags

flag provided but not defined: -terragrunt-non-interactive

For more help on using this command, run:
  tofu apply -help

Either the default options should be part of the digger.yml workflow config, or they need to be configurable or auto-selected based on the terragrunt version.

Hey @languitar thanks for flagging this! I think we can replace that flag with env variable and include both $TERRAGRUNT_NON_INTERACTIVE and $TG_NON_INTERACTIVE. Happy to accept contributions here!
