Skip web fonts in module javadocs

Prior to this commit, module javadoc packages like
"spring-core-7.0.8-javadoc.jar" would contain 4MB of web fonts in the
`resource-files/fonts/` folder. This increases significantly (often
doubles) the size of the javadoc JAR for little value.

With this commit, Web fonts are packaged with the aggregated Javadocs
for the entire Spring Framework project, but are skipped for inidividual
modules.
