Update version to 4.0.0

This update contains several new features:

* Support for Java records
* Support for File, Path, URL, URI, Instant
* New project structure that makes it easier to add support
  for additional file types

... and some breaking changes:

* The code for saving and loading YAML files was moved from the
  configlib-core to the configlib-yaml module:
  * The Configurations class has been renamed to YamlConfigurations
    and its methods lost their -YamlConfiguration affix.
* FieldFormatter has been renamed to NameFormatter
