ZOOKEEPER-2862: Incorrect javadoc syntax for web links in StaticHostProvider.java.

Javadoc does not offer any special tagging for web links - the "link" etc is for linking with other javadocs of the classes / methods. Use normal html markup instead.

This fixes warning messages generated when running "ant javadoc". Verified generated javadoc that the web link is functional.
