Use HTTP for localhost registry

[rellfy]

Is there a way to use http (instead of https) for a localhost registry? Looks like the default_registry field in the settings file only accepts an origin so it fails to parse if prefixed by e.g. http://.

In the README I see that it's possible to use the http protocol for the OCI registry:

[registry."acme.registry.com".oci]
# This is an optional field that tells the OCI client to use a specific http protocol. If this is
# not set or not one of the accepted values of "http" or "https", then the default (https) will
# be used.
protocol = "https"

I tried using this for a warg registry but it didn't seem to work.
