Forward slashes replaced by backslash for within inline hook scripts

[wbreza]

When defining an azd inline script hook (command or service) forward slashes are mistakenly replaced by back slashes causing scripts to failed unexpectedly. Inline scripts should not be modified.

Repro

1. Create azure.yaml with the below snipped:
2. Run azd package command or whichever command hook is configured for
3. Hook will fail about an invalid hostname

azure.yaml

# yaml-language-server: $schema=https://raw.githubusercontent.com/Azure/azure-dev/main/schemas/v1.0/azure.yaml.json

name: todo-nodejs-mongo-aca
metadata:
  template: todo-nodejs-mongo-aca@0.0.1-beta
hooks:
  prepackage:
    shell: pwsh
    run: Invoke-WebRequest -Uri "https://sample.com/sample.json" -OutFile "out.json"
services:
  web:
    project: ./src/web
    language: js
    host: containerapp
  api:
    project: ./src/api
    language: js
    host: containerapp

Expected

Hook should run and invoke the web request without any issues

Actual

Hook fails with message
