feat: implement dynamic defaulting feature
- file/codegen/main.go and corresponding schema change This is to relax the schema of kong entities that are used as input for defaults. The relaxation is necessary as otherwise the user will have to specify a name in default values. This doesn't have any side-effects because the *kong.Type is not used anywhere else in Content. - file/builder.go file/reader.go - defaulter instantiation has been moved inside builder, this feels natural, defaulter being instantiated outside the builder seems odd and the only explanation is that I simply didn't think through when implementing defaulter - other changes override the default values that are registered Fix #89
