MINOR: Fix for typos in processor-api.html (#6961)

This PR intendent to address some typos in https://kafka.apache.org/documentation/streams/developer-guide/processor-api.html page.

Invalid configuration option specified in the example. I've replaced with closest constant TopicConfig.MIN_IN_SYNC_REPLICAS_CONFIG, since LogConfig.MinInSyncReplicasProp() requires Scala stuff
Reference to LogConfig seems to be obsolete, I believe I've moved it to correct line
Apostrophe displayed incorrectly
