Handling of Carriage Return (`\r`) in a double-quoted string differs from `gopkg.in/yaml.*.`

Hi @goccy !

I found that handling carriage return ( \r ) in a string differs from gopkg.in/yaml.*. .

Input:

var: "hello\r\nworld"

Unmarshal Result:

goccy/go-yaml 1.11.0	gopkg.in/yaml.v2	gopkg.in/yaml.v3
map[string]interface {}{"var":"hello\\r\nworld"}	map[interface {}]interface {}{"var":"hello\r\nworld"}	map[string]interface {}{"var":"hello\r\nworld"}

Playground is https://go.dev/play/p/Q-cdur6z8B9

Is this the intended behavior?
