Description of GC logging needs to be updated in "Configuration guide".

• Name of GC log file can't be changed. File size of GC log is 3MB and can't be changed in supported way. So this part of "12.1.3. Garbage Collection Logging" chapter:

  The default location for the garbage collection log is EAP_HOME/standalone/log/gc.log.DIGIT.current. By default, garbage collection logs are limited to three MB each, and up to five files are rotated. 
  

  Needs to be changed to:

  Location for the garbage collection log is EAP_HOME/standalone/log/gc.log.DIGIT.current. Garbage collection logs are limited to three MB each, and up to five files are rotated. 
  

• Correct file name of GC logs are gc.log.DIGIT.current. This name is wrong in "Table 12.1. Default Log File for a Standalone Server"
