[BUG] openapi-generator-gradle-plugin ignores changes in templates

Created by: neopaf

Description

When I change files in templates folder

    templateDir = "templates"

I expect task to be triggered. But it goes "UP-TO-DATE"

openapi-generator version

5.4.0

Generation Details

Suggest a fix

Workaround:

    inputs.dir 'templates'

But it should not be necessary, right?
