[BUG] Elsa 2 swagger error for IFormFile

[JoschaMetze]

Description

Generating a swagger api doc with the latest swashbuckle (Swashbuckle.AspNetCore.SwaggerGen 6.6.2) will cause a generation error due to the use of [FromForm] IFormFile in the WorkflowDefinition Import and Restore-Controller.

Steps to Reproduce

To help us identify the issue more quickly, please follow these guidelines:

Update sample to latest swashbuckle and try to produce swagger documentation, the following exception will occur:
Swashbuckle.AspNetCore.SwaggerGen.SwaggerGeneratorException: Failed to generate Operation for action - Elsa.Server.Api.Endpoints.WorkflowDefinitions.Import.Handle (Elsa.Server.Api). See inner exception ---> Swashbuckle.AspNetCore.SwaggerGen.SwaggerGeneratorException: Error reading parameter(s) for action Elsa.Server.Api.Endpoints.WorkflowDefinitions.Import.Handle (Elsa.Server.Api) as [FromForm] attribute used with IFormFile. Please refer to https://github.com/domaindrivendev/Swashbuckle.AspNetCore#handle-forms-and-file-uploads for more information

If you follow the link you will find documentation that [FromForm] should not be used with IFormFile. Removing the attribute solves the issue.

Relevant code signature:
public async Task<IActionResult> Handle(string workflowDefinitionId, [FromForm] IFormFile? file, CancellationToken cancellationToken) {

Thanks for looking into this.
