Motivation

gopkg.in/yaml.v3 is deprecated: https://github.com/go-yaml/yaml/tree/v3

Changes

Replace all direct imports with go.yaml.in/yaml/v3 v3.0.4, which is the same code under the supported new module path. The old module path remains as an indirect dependency of transitive deps.

$ go mod why -m  gopkg.in/yaml.v3
# gopkg.in/yaml.v3
github.com/argoproj/argo-cd/v3/notification_controller/controller
github.com/argoproj/notifications-engine/pkg/api
gopkg.in/yaml.v3

Same question/comment as in argoproj/notifications-engine#436.

LGTM otherwise

[thevilledev]

Detailed answer in argoproj/notifications-engine#436 (comment) but short version, a lot of dependencies still rely on the unmaintained library (like testify) and the indirect references will probably stay for a while.

Thanks!
