FeatureHasher and HashingVectorizer does not expose requires_fit=False tag #30689

Description

@glemaitre

While FeatureHasher and HashingVectorizer are stateless estimator (at least in their docstrings), they do not expose the requires_fit tag to False as other stateless estimator.

@adrinjalali Do you recall when changing the tags if there was a particular reason for those estimator to not behave the same way than others?
