Walkthrough

This PR migrates the YAML library dependency from gopkg.in/yaml.v2 to gopkg.in/yaml.v3 across the codebase. Import statements are updated in controllers/secret_controller.go, its test file, pkg/types/alertmanagerconfig.go, and test/e2e/utils/utils.go, with go.mod updated accordingly, retaining yaml.v2 as an indirect dependency.

Changes

YAML dependency migration

Layer / File(s)	Summary
Dependency declaration update go.mod	Direct requirement changes from gopkg.in/yaml.v2 v2.4.0 to gopkg.in/yaml.v3 v3.0.1; yaml.v2 v2.4.0 is added back as an indirect dependency.
Source file import updates controllers/secret_controller.go, pkg/types/alertmanagerconfig.go	YAML imports switch to yaml.v3, changing the implementation backing existing Marshal/Unmarshal calls for namespace config and Alertmanager config handling.
Test and e2e utility import updates controllers/secret_controller_test.go, test/e2e/utils/utils.go	YAML imports switch to yaml.v3 in test and e2e utility code, changing the implementation backing YAML parsing in tests.

🐰 Hopping through imports, swift and spry,
v2 to v3, waving goodbye,
Marshal and parse with a newer might,
go.mod tidied up just right,
A carrot for clean YAML delight! 🥕
