Making Old Ext work for recent PhpBB Version !

[manigopal]

I could see mostly the same error throws for older extensions that doesn't support for newer versions of PhpBB 3.3.x (likely 3.3.4). So it will be really useful if any of the moderators / developers of PhpBB makes a general note on how to fix this issue.

```
phpBB encountered an error building the container due to an installed extension. For this reason, all extensions have been temporarily disabled. Please try purging your forum cache. All extensions will automatically be re-enabled once the container error is resolved. If this error continues, please visit phpBB.com for support.

Exception: The file "C:\xampp\htdocs\myBoard\ext\rmcgirr83\zodiacs\config\services.yml" does not contain valid YAML: The reserved indicator "@" cannot start a plain scalar; you need to quote the scalar at line 5 (near "- @config").
