Possibility to configure temporal test server host

[cv65kr]

Why?

To have possibility to change default port for temporal test server. Also: Since output of RR is not visible in PHPunit sometimes it's hard to figure out where is the error. So you can switch test server to real temporal server and see in UI what's happened. Alternatively Datadog offers https://github.com/temporalio/temporalite own server which also can be use for tests purposes.

Maybe it can be moved to env variable in phpunit.xml file? 🤔 Instead of hardcoding or passing around variables.

That was my original idea, but I was a bit confused why it was hard coded on beginning 🤔 Anyway updated
