character '-' as string is interpreted as the beginning of a list

[Diliz]

Describe the bug

When the value of an attribute is "-", what's next of this attribute seems to be rendered as a part of a list, which is not the case.

To Reproduce
Use the following yaml:

cat: -
dog: -
bark: "woof"

Unmarshaling then encoding it will be rendered as:

cat:
  - dog:
    - bark: "woof"

Here an example: https://go.dev/play/p/4IazOu5k7YA

Expected behavior

This should be rendered as:

cat: "-"
dog: "-"
bark: "woof"
