RFR 8205927: Update src/java.base/share/legal/public_suffix.md to match the actual file version

[Weijun Wang]

Please take a review at

   http://cr.openjdk.java.net/~weijun/8205927/webrev.00/

I missed a date and a link when pushing the change for JDK-8201815. Also, the 
latest MPL 2.0 uses https now.

Thanks
