Description of the bug

Hi,

All my backends are written spring boot. The spec files are generated dynamically and they don't have extensions, for example http://localhost:8088/doc/v2

So I have to download, rename and copy the spec file when I need to use the plugin, which is unproductive.

When I use the openapi generator maven plugin it works fine with extensionless remote specs, and since this plugin also uses openapi-generator-cli.jar, my suggestion is to change the plugin specific logic to detect the if the spec file is json or yaml to validate by the mime type instead of the extension.

Thanks
