RFR 9: 8129744 : Documentation in Month refers to quarters

[Roger Riggs]

Please review two java.time editorial changes:
   - 8129744: a trivial editorial change in java.time.Month javadoc.
   - 8129556: TemporalAdjusters dayOfWeekInMonth wrongly says "in the 
same month"

Issue:
   https://bugs.openjdk.java.net/browse/JDK-8129744

Thanks, Roger
