PrettyPrint configuration is not picked up from config file

[mjaggard]

The documentation here: https://github.com/swagger-api/swagger-core/tree/master/modules/swagger-maven-plugin
states that prettyPrint can be set in the configuration file but it is actually ignored and must be set in the pom.xml file.

This line reads directly from the Maven config rather than the parsed configuration file:

swagger-core/modules/swagger-maven-plugin/src/main/java/io/swagger/v3/plugin/maven/SwaggerMojo.java

Line 101 in f1fcdc2

if (prettyPrint != null && prettyPrint) {
