Create bash script to generate app-config.local.yaml file from template

Here is the template that we should use:

# Backstage override configuration for QShift

organization:
  name: QShift

app:
  title: QShift Backstage App
  baseUrl: ${BACKSTAGE_URL}:3000 (we add the port only for localhost)

backend:
  baseUrl: ${BACKSTAGE_URL}:7007 (we add the port only for localhost)
  listen:
    port: 7007
  csp:
    connect-src: ["'self'", 'http:', 'https:']
    # Content-Security-Policy directives follow the Helmet format: https://helmetjs.github.io/#reference
    # Default Helmet Content-Security-Policy values can be removed by setting the key to false
  cors:
    origin: http://localhost:3000
    methods: [GET, HEAD, PATCH, POST, PUT, DELETE]
    credentials: true
  # This is for local development only, it is not recommended to use this in production
  # The production database configuration is stored in app-config.production.yaml
  database:
    client: better-sqlite3
    connection: ':memory:'
  auth:
    # Used for enabling authentication, secret is shared by all backend plugins
    # See https://backstage.io/docs/auth/service-to-service-auth for
    # information on the format
    keys:
      - secret: Tg3vL6P2w74xP/fcSpmv0ulZw2Lx1wsr

auth:
  # see https://backstage.io/docs/auth/ to learn about auth providers
  providers: {}

proxy:
### Example for how to add a proxy endpoint for the frontend.
### A typical reason to do this is to handle HTTPS and CORS for internal services.
# endpoints:

#     target: 'https://example.com'
#     changeOrigin: true

# Reference documentation http://backstage.io/docs/features/techdocs/configuration

# and an external cloud storage when deploying TechDocs for production use-case.
