The starting example gives panic

[axilis-marko]

Issue Description

I've tried running the starting example from README with just the health endpoint. It panics on gen.Parse.

Steps to Reproduce

1. run the following code

package main

import (
	"github.com/gin-gonic/gin"
	"github.com/ls6-events/astra"
	"github.com/ls6-events/astra/inputs"
	"github.com/ls6-events/astra/outputs"
)

func main() {
	r := gin.Default()

	r.GET("/health", func(c *gin.Context) {
		c.JSON(200, gin.H{
			"status": "ok",
		})
	})

	gen := astra.New(inputs.WithGinInput(r), outputs.WithOpenAPIOutput("openapi.generated.yaml"))

	// For OpenAPI to work, we need to define a configuration, which contains the title, version and description amongst other important information
	config := &astra.Config{
		Title:   "Example API",
		Version: "1.0.0",
		Host:    "localhost",
		Port:    8000,
	}

	// Either way, you need to set the config for the OpenAPI generator to use
	gen.SetConfig(config)


	err := gen.Parse()
	if err != nil {
		panic(err)
	}

	err = r.Run(":8000")
	if err != nil {
		panic(err)
	}
}

Expected Behavior

For it to not panic and give an OpenAPI spec.

Actual Behavior

It panics after the error is returned on gen.Parse().

Output:
