filename reference in error output

**What steps did you take:**

Deploying a set of spec files where one of them has an error. No idea which one...

**What happened:**

There is no reference in the error message to the file or even line to be able to trace back the issue.

```
kapp: Error: Trying to apply empty set of resources will result in deletion of resources on cluster. Refusing to continue unless --dangerous-allow-empty-list-of-resources is specified.
```
or:
```
╰─➤ kapp app-group deploy -g all -n default --directory kappsvc -c
kapp: Error: error unmarshaling JSON: json: cannot unmarshal string into Go value of type map[string]interface {}
```

**What did you expect:**

like kubectl reference the filename and the line where this problem occurs

**Environment:**

- kapp version 0.50.0
- OS Ubuntu 22.04
- Kubernetes version 1.22
