Issue:
Documentation for find_in_parent_folders() should document folder-finding functionality
**Describe the bug**
[The Terragrunt docs](https://terragrunt.gruntwork.io/docs/reference/built-in-functions/#find_in_parent_folders) state that the function `find_in_parent_folders()` can optionally be supplied with a `name` parameter which,
> allows you to specify a different filename to search for
However, it appears the function is intended to be able to find folders as well as files, as "fixed" in https://github.com/gruntwork-io/terragrunt/issues/2868

**To Reproduce**
This is a documentation issue, so the issue can be reproduced by viewing the documentation [here](https://terragrunt.gruntwork.io/docs/reference/built-in-functions/#find_in_parent_folders)

**Expected behavior**
We expect the documentation to tell the user this additional behavior is possible.

**Versions**
The additional functionality has been available since [v0.54.12](https://github.com/gruntwork-io/terragrunt/pull/2869).

 You can also pass an optional second `fallback` parameter which causes the function to return the fallback value (instead of exiting with an error) if the file in the `name` parameter cannot be found:
 
 ``` hcl
