resolve flag not working for destination target in oras cp

[qweeah]

What happened in your environment?

--resolve will not work for the destination target, below command will fail to lookup $TO.

oras cp $FROM:v1 $TO:v1 --resolve $TO:443:127.0.0.1

What did you expect to happen?

Should not lookup $TO and use the customized $TO->127.0.0.1 mapping provided by --resolve.

How can we reproduce it?

Setup $FROM and $TO with registry name and run below command

oras cp $FROM:$TAG $TO:$TAG --resolve $TO:443:$ADDR
