Open API v2 Server URL

[ellyxc]

Context

Swagger v2 host and schemas are not mandatory (at least from documents i could find). But the following transformer is requesting them

http-spec/src/oas2/transformers/servers.ts

Lines 32 to 36 in f5594fb

	if (typeof host !== 'string' || host.length === 0) {
	return;
	}
	if (!isString(scheme) || !isValidScheme(scheme)) return;

Current Behavior

It is not returning server address

Expected Behavior

It is using current browser host as server url, or basePath only similar to OAS v3
