bugfix: openapi code generator to consider schema changes

[DeepikaSridhar2112]

Issue description : OpenApi code generator fails to regenerate the classes when changes are made to schema specifications.

Analysis: Open Api code generator task, org.openapitools.generator.gradle.plugin.tasks.GenerateTask is present in openapi-generator-gradle-plugin-5.4.0.jar. It scans changes across parameters provided as inputs and determines if code has to be regenerated on invocation.If schema changes made directly in openapi.yml it detects the change and re-generates the code. However it isnt aware of the location of the schema files refered via reference($ref) tags. Hence the open api code generator doesn't detect changes made to schema files.

Resolution: Adding schema location as an parameter to GenerateTask.kt resolves the issue. The plugin when executed detects changes made to reference schema files

@wing328 We have been running into problems where we've split a large OpenAPI specification into numerous files, with a file for each object. These are all in various sub folders and pulled in using $ref: "/.schemas/foo.yml for example. Without marking the schema folder as an input directory for the generate task, Gradle will use it's cache since it doesn't think any inputs have changed, despite you making changes to foo.yml.

How would you suggest we add a test for this? I assume you already have tests covering how you import schemas via reference, and this change is around the Gradle caching when a change has been made after your first build.

@wing328 what would you suggest we do for a test on this as requested?
