[Yaml] Allow tabs as separators between tokens

As described in #40507, the Yaml spec allows tabs as whitespace characters between tokens. However, the Yaml parser crashes on this as it only expects spaces after the colon. https://yaml.org/spec/1.2/spec.html#id2778241

While I'm not a huge fan of it personally, it's an issue when a different linter tells us that a given YAML file with content that we have little control over has valid syntax in an unrelated check, and then our app crashes because it cannot be parsed after all.
