fix(http): load TLS CA roots from OTP public_key
Some checks failed
Deploy Docker Images / Build, push, and deploy (push) Has been cancelled

Browse source 
Moving hackney (and its certifi dep) out of the prod release left
GunPool calling missing :certifi.cacerts/0, which crash-looped the app
and caused edge 502s. Use :public_key.cacerts_get/0 like the rest of
the TLS client stack.
