RFR: XS,doc JDK-8225306 bad headings in java.sql.rowset SyncProvider.java

[Jonathan Gibbons]

Please review a tiny doc fix to make the headings in this file consistent.

The headings are currently:

$ grep 'h[1-6]' 
open/src/java.sql.rowset/share/classes/javax/sql/rowset/spi/SyncProvider.java
  * <h3>1.0 Naming Convention for Implementations</h3>
  * <h2>2.0 How a <code>RowSet</code> Object Gets Its Provider</h2>
  * <h2>3.0 Violations and Synchronization Issues</h2>
  * <h2>4.0 Updatable SQL VIEWs</h2>
  * <h2>5.0 <code>SyncProvider</code> Constants</h2>


The first one should be changed to <h2>.

No webrev; patch below.
