Speed up retrofit related long running tests (arrow-kt#2908)

Issue

This is a part of changes related to #2908 issue.

Description

Current PR raised to fix next long running tests connected with retrofit http client:

     should return IOError when no responsearrow.retrofit.adapter.either.networkhandling.NetworkEitherCallAdapterTestSuite:arrow-core-retrofit:test | PASSED | 10.889s
 (2) should return IOError when no responsearrow.retrofit.adapter.either.networkhandling.NetworkEitherCallAdapterTestSuite:arrow-core-retrofit:test | PASSED | 10.041s
 (1) should return IOError when no responsearrow.retrofit.adapter.either.networkhandling.NetworkEitherCallAdapterTestSuite:arrow-core-retrofit:test | PASSED | 9.448s

After changes I see next timings on my local machine:

    should return IOError when no response	0.237s	passed
(1) should return IOError when no response	0.204s	passed
(2) should return IOError when no response	0.203s	passed

Root cause

Out of the box retrofit is using default OkHttpClient if no other client passed during creation. Meanwhile OkHttpClient has default value of read timeout that is equal to 10 seconds.
As a fix - decreased read timeout to 0.2 seconds
