RFR: 8283889: Fix typo in package-info.java

[Lance Andersen]

Hi all,

Please review this trivial fix which addresses a typo in src/java.sql/share/classes/java/sql/package-info.java

make docs is clean and I am also running mach5 tier1 as an extra sanity check so there are no surprises when the patch is pushed

Best
Lance
