What this PR does / why we need it:

Fix for (#10597)

Added 2-way TLS Support for oci pull for artifact repository which causes TLS handshake failure error.
Special notes for your reviewer:

Added flag for two-way authentication (--tls-enabled) .
 example:- helm pull oci://nginx.testharbor.com/testrepo/sslcharttest --version 0.1.0  --ca-file /etc/docker/certs.d/nginx.testharbor.com/ca.crt --cert-file /etc/docker/certs.d/nginx.testharbor.com/root_client.crt --key-file /etc/docker/certs.d/nginx.testharbor.com/root_client.key --mtls-enabled
