<i18n dev> [14] RFR (XXS) 8238605: Correct the CLDR version number in cldr.md files

[naoto.sato at oracle.com]

Hello,

Please review this extra small fix for this issue:

https://bugs.openjdk.java.net/browse/JDK-8238605

The proposed changeset is located at:

http://cr.openjdk.java.net/~naoto/8238605/webrev.00/

It is simply updating the version number in cldr.md files, which should 
have been done with JDK-8231273.
