Add date when creating instal script

It would be useful to have date and other info as a comment on created install scripts:

```
# author: https://github.com/bradhawkins85
# created on 2025-04-09 11:05:43 by user Operator1
$innosetup = 'tacticalagent-v2.9.0-windows-amd64.exe'
```

thanks for your time
