Error Message For Edit Command Can be Clearer

[MarcusGitty]

How to reproduce the bug:

Type in edit i:0 n/pap

Issue: Index should be a positive integer.

A more specific error message could be, the index you have entered is not a positive integer instead of invalid command format.

Cuz technically, the command format follow the format, just that the index is invalid. So perhaps the error can be like this, saying the index is invalid

• [x] I disagree

Reason for disagreement: The original bug is talking about the consistency of error message while i'm reporting the specificity of it

## :question: Issue type Team chose [`type.DocumentationBug`] Originally [`type.FeatureFlaw`] - [x] I disagree **Reason for disagreement:** [replace this with your reason] This is regarding the Specificity of error message and as per the course website it should be a feature flaw. 

---

## :question: Issue severity Team chose [`severity.VeryLow`] Originally [`severity.Low`] - [x] I disagree **Reason for disagreement:** As per the course textbook "Calling an invalid value a 'format error' and vice versa is a severity.Low bug" this is such a case, therefore it should be severity.Low
