Support for adders instead of setters for Collections record components

[sashirestela]

This functionality is about to include "adders" methods (instead of setters) to builders for record components of Collection type. For better usability, it would be necessary to create a new annotation such as @Builder.Singular(value=optionalSingularName) to indicate what record components will be singularize and optionally to indicate what singular name to use in case it cannot be deducted from the plural name.

For example:

public record Project(Integer id, String name, @Build.Singular List<String> members) {}

Project project1 = ProjectBuilder.builder()
    .id(101)
    .name("Special Project")
    .member("Rose")
    .member("Jack")
    .build();

The rules to deriving singular forms from plural words in English are:

• Words ending in "ves", replace "ves" with "fe". Ex: lives → life
• Words ending in "ies", replace "ies" with "y". Ex: cities → city
• Words ending in "es", remove "es". Ex: boxes → box
• Words ending in "s", remove "s". Ex: names → name
• Any other case should require to indicate an explicit singular name.
