[Feature Request]: Enhanced Configuration File Selection in Environment Properties

### What would you like to happen?

I would like to request an enhancement for the way **configuration files** are added in **Environment Properties**.

Instead of selecting **individual** files manually, it would be great if the selection worked similarly to the **JSON Input** transform.

Specifically, it would be helpful to have the following options:

- File/Directory Selection (allowing users to select an entire folder)
- Wildcard (RegExp) to filter specific files
- Exclude Wildcard to ignore certain files
- Required flag for mandatory files
- Include Subfolders option to process files in subdirectories

**_This would greatly improve usability and flexibility when managing configuration files._**

**Currently**:


**After feature implementation**:


NOTE:
It would also be great to have this functionality for the **_hop-conf_** script.

Example:

```
$ sh hop-conf.sh \
--environment-create \
--environment test-file \
--environment-project test-file \
--environment-purpose=Testing\
--environment-config-file-directory="/config"
--environment-config-file-wildcard="*.json"
```
