Adding --insecure-skip-tls-verify still fails for client

[axelfontaine]

When using the gosmee client to forward to a local dev process using https with a self-signed certificate, it fails with tls: failed to verify certificate: x509: certificate signed by unknown authority regardless of whether --insecure-skip-tls-verify is set or not.

Example command:

gosmee --insecure-skip-tls-verify client https://smee.io/abc https://localhost:8443/github/webhook
