fix(amazonq): use fsPath for project name #6176

## Problem
Issues reported in chat sometimes does not match issues tree.

This is happening because the zip artifact uses workspace name (custom
name could be different from fsPath) while git diff output uses fsPath.
This causes the findings to come back as two filePaths that end up
overwriting each other.


## Solution
Update zip to use project name from fsPath instead of
`workspaceFolder.name`
