fix: close HTTP resp body to prevent resource leak (#4857)

This PR fixes possible resource leaks by adding a statement that closes
a response body.

From the [documentation](https://pkg.go.dev/net/http):
> The caller must close the response body when finished with it

Also, see this
[article](https://golang50shad.es/index.html#close_http_resp_body) for a
deep dive into the problem.
