scalarConfig.spec.url is resolved incorrectly when the path option contains a subdirectory.

The changes introduced in #59 breaks in the case where swagger is mounted with path in the subdirectory.

const app = new Elysia()
  .use(
    swagger({
      path: "/services/docs",
    })
  )
  .get("/services/hello", () => ({ ok: true }));

When going to /services/docs, I get a blank page. This is because Scalar tries to load the data from /services/services/docs/json.

Current workaround is to manually override the scalarConfig

const app = new Elysia()
  .use(
    swagger({
      path: "/services/docs",
      scalarConfig: {
        spec: { url: "/services/docs/json" },
      },
    })
  )
  .get("/services/hello", () => ({ ok: true }));
