fix: allow latest terragrunt

[abdulhaq-e]

Description

The current checks for supported version fails if terragrunt has been built from source. This is because the command terragrunt --version outputs "terragrunt version latest" which fails the comparisons and stops the pre-commit hook from running.

This PR fixes the version check by searching for "latest" in the version output first.

Note: The code changes have been suggested by Gemini, I only made minor edits.
