regclient may leak authentication credentials to external blob stores

regclient is a Docker and OCI Registry Client in Go. Prior to version 0.11.5, credentials for a registry may be inadvertently leaked to external servers. A prerequisite for this attack is a malicious registry server, a malicious blob store, or a registry that does not restrict the external URLs for foreign blobs. Version 0.11.5 fixes the issue.
