[BUG] MicrometerObservationCapability not reporting timeouts

Describe the bug Feign cloud version: 4.1.0

When using the MicrometerObservationCapability, anyjava.net.SocketTimeoutException is not caught and observations is never closed (MicrometerObservationCapability#enrich only catches FeignExceptions). Probably affects other errors from the underlying web layer too. The result is that these requests are never added to the metrics. There is either an ordering error, or MicrometerObservationCapability should catch more types of errors

Sample No specific config added. Plain FeignClients

@FeignClient(name = "NAME", url = "${url.prop}")
interface Client {
// calls here
}

@Configuration
class FeignConfig {
  @Bean
  def observation(observationRegistry: ObservationRegistry): MicrometerObservationCapability = new MicrometerObservationCapability(observationRegistry, new DefaultFeignObservationConvention())
}

application.yml

spring:
  cloud:
    openfeign:
      client:
        config:
          default:
            connect-timeout: 3000
            read-timeout: 3000
