[CI:DOCS] socket_activation.md: increase socat timeout

Browse Source 
The default socat timeout is 0.5 seconds.
Make the socket-activate-echo example in socket_activation.md
more robust by increasing the socat timeout.

```
The option `-t 30` configures socat to use a timeout of 30 seconds when socat reads from the socket awaiting to get an EOF (End-Of-File).
As the container image has already been pulled, such a long timeout is not really needed.
The echo server works as expected. It replies _"hello"_ after receiving the text _"hello"_.
### Example: socket activate an Apache HTTP server with systemd-socket-activate
