Overview of the Issue

Hi,

We have a project that we are using the terragrunt workflow and the '--autoplan-file-list' flag does not consider *.json, *.yaml, *.yml files that are in subdirectories of the terragrunt structure.

Our file structure follows this format:

.
└── live
    ├── prod
    │   ├── main.tf
    │   ├── terragrunt.hcl
    │   └── policies
    │       └──iam.json
    └── staging
        ├── main.tf
        ├── terragrunt.hcl
        └── policies
            └──iam.json

If we change a value in the iam.json file, atlantis does not detect the file change and does not perform the 'auto plan'.

We have already added the values that detect this modification to the '--autoplan-file-list' flag. Example:
**/config\\-*.json, so the plan goes to the policies directory and not the prod directory.

Reproduction Steps
