Add option to provide custom WS config in zio-http

[kyri-petrou]

Attempt at #3290.

@adamw I'm not sure what would be the best way to test these changes, do you have any suggestions? Also, the addition of the argument in ZioHttpServerOptions makes this a breaking change. Should we add the default value to the constructor of ZioHttpServerOptions to make it at least source compatible?

[adamw]

We don't have any compatibility requirements for this module (see https://tapir.softwaremill.com/en/latest/stability.html).

That's especially true for zio-http - every release (RC or not) usually means a major rewrite of the source code ;)

Which is to say: it's not a problem to add new options

Ah nice, wasn't aware of this - that's good to know!

@adamw tests for Scala 3 seem to be failing but I'm not entirely sure why. Any chance that's due to test flakyness?

[adamw]

Thanks :) Indeed, seems the test was flaky
