[Kword] Generated dir error

[npresseault]

Description

Fix issue with kword directory which should have been marked as output directory instead of input.

Motivation and Context

Fixes this error when the directory does not exist

> Task :app:shared:kwordGenerateEnum FAILED

FAILURE: Build failed with an exception.

* What went wrong:
A problem was found with the configuration of task ':app:shared:kwordGenerateEnum' (type 'KWordEnumGenerate').
  - In plugin 'mirego.kword' type 'com.mirego.kword.KWordEnumGenerate' property 'generatedDir' specifies directory 'generated' which doesn't exist.
    
    Reason: An input file was expected to be present but it doesn't exist.
    
    Possible solutions:
      1. Make sure the directory exists before the task is called.
      2. Make sure that the task which produces the directory is declared as an input.
    
    For more information, please refer to https://docs.gradle.org/8.8/userguide/validation_problems.html#input_file_does_not_exist in the Gradle documentation.

How Has This Been Tested?

Tested in sample, by removing the directory manually.
