Description

When using the openapi-generator-maven-plugin on Windows with an inputSpec as an URL with query parameter(s), the plugin failed.
The plugin tries to create a file named 'swagger.yaml?resolved=true-petclinic.sha256' which is not allowed on Windows.

On MacOS, there is no issue.

The filename generation for the sha256 should replace/remove invalid characters for the executing platform or not take the URL part with the query parameters (as in version 7.6.0)
