Issue:
Deprecated: Using ${var} in strings is deprecated
When I start up the docker container and it's running, I access the website and see this error:

```Deprecated: Using ${var} in strings is deprecated, use {$var} instead in /src/app/index.php on line 157```

It's a simple change so I'll create a PR


Discussion / hints:

Fix patch:
