[Bug]: import metadata issue

[kvnhmn]

Bug Description

I export the flags with the following command: /opt/flipt/flipt export --config /opt/flipt/flipt.yml --all-namespaces -o backup-flipt-export.yaml

and then import them as follows: /opt/flipt/flipt --config /opt/flipt/flipt.yml import --drop backup-flipt-export.yaml

but get the error: Error: proto: invalid type: map[interface {}]interface {}

Flipt uses gopkg.in/yaml.v2 which convert data to map[any]any and protobuf expects map[string]any.

Version Info
