Increase timeouts to prevent flakiness

[sankari165]

What changed?
Increasing timeouts for activity tasks in testing workflow based internal rate limits

Why?
Activity tasks have been timing out and failing the tests flakily. These tasks are actually ratelimited and retried by history so need to have bigger timeouts configured. The cache works on one second TTL

How did you test it?
Integration tests
