Use stdlib HTTP::Client for automatic redirect

`make_client` is affected by the `force_resolve` configuration option.
However, as api.invidious.io does not support ipv6 it leads to an error
whenever force_resolve is set to only use ipv6.

The stdlib HTTP::Client however is not effected by the force_resolve
configuration and therefore remains unaffected
