IO::Error no parameter named 'cause'

[jwoertink]

Maybe a regression? This compiles fine in Crystal 1.10.1, but fails to compile in Crystal 1.11.1

error = Exception.new("oops")
IO::Error.new("parsing proxy initialization", cause: error)

In lib/connect-proxy/src/connect-proxy.cr:134:23

 134 | raise IO::Error.new("parsing proxy initialization", cause: error)
                       ^--
Error: no parameter named 'cause'

Overloads are:
 - IO::Error.new(message : String | ::Nil = nil, *, target = nil)

I opened an issue here spider-gazelle/connect-proxy#4

Yeah, this is caused by #13865 which introduces a new def IO::Error#initialize. This removes all inherited #initialize defs from IO::Error, which means the implementation from Exception with cause parameter isn't available anymore.
