Description

PartialFunction is a pain to use in Java and for recoverWith a simple Class<Throwable> parameter would be sufficient.

Similar with mapError. Class<Throwable> parameter and a Function<Exc, Throwable>

By the way, I suggest removing the deprecation of recoverWith since I think in most of the time the attempt count is not interesting, especially since there is no reset of the count or notion of failures per time unit.

Contributor guide

Research direction
Examine the existing recoverWith implementation in the Java DSL and identify how to replace PartialFunction with a Class<Throwable> parameter. Also review the deprecation rationale for recoverWith and consider removing it.
