Major Changes

• b1974f0: build: parse yaml with more strict multiline indentation rules

  Internal dependencies of js-yaml@v5 make YAML parsing more strict and compliant with the YAML specification. Indentation is now required for values that span multiple lines against the base value.

  See the YAML line prefixes spec for the expected indentation rule:

    channel: "C0123"
    text: "first line
  
  - second line"
  +   second line"
