Redundant Path annotation when router grouping pattern exists

For Speakeasy, we need to annotate each handler with // @Router /v1/endpoint/path_a [post] . However, we already have this information because each of our routes has a Pattern with the same information

router.Route{
					Name:       "name of handler",
					Method:     http.MethodPost,
					Pattern:    "/v1/endpoint/path_a",
					APIHandler: apiApp.Handler,
},

It would reduce redundant dev work if we didn't need to have the extra annotations in both places

Acceptance Criteria:

• Code parser should recognise the presence of a route grouping and automatically infer path information
