/**
 * The purpose of this extension is to fix invalid metadata saved to either antora.yml or gradle.properties in certain
 * tags. This invalid metadata prevents Antora from classifying the component versions properly.
 *
 * This extension addresses with the following cases:
 * 
 * . the boolean value on the prerelease key is incorrectly quoted
 * . the prerelease tag is set to true for a GA version
 * . the value of the name key is empty
 * . the value of the displayVersion key doesn't match the actual version
 * . the -SNAPSHOT suffix is appended to the value of the version key instead of the value of the prerelease key
 *
 * This extension should be listed directly after @antora/collector-extension.
