Scalar Node with Literal style encodes as Double-quoted when value has a line with trailing spaces #78
Description
Note: this is a clone of go-yaml/yaml#880, with slight modification to make it more succinct.

)
func main() {
data, _ := os.ReadFile("data1.yaml")
ymlData := make(map[string]any)

newData, _ := yaml.Marshal(ymlData)
fmt.Println(string(newData))
}output yaml:

multi-line-string-with-trailing-tab-chars: |
this line does not have trailing whitespace
this line has trailing tab characters
this line does not have trailing whitespace
multi-line-string-without-trailing-whitespace: |
this line does not have trailing whitespace

this line does not have trailing whitespace
Observed behaviors:
- string blocks that have lines with trailing space (0x20) characters will be converted into double-quoted strings. Trailing spaces are preserved.
- string blocks that have lines with trailing tab (0x09) characters will remain as a string block. Trailing tabs are preserved.
Expectations:
- string blocks that have lines with trailing space (0x20) characters would remain string blocks, and their trailing spaces would be preserved.
