This pull request introduces HuggingFace as a new sentiment analysis provider for the crowd.dev platform. It adds a feature flag NEW_SENTIMENT to toggle between the old and new providers. It also adds the axios library as a dependency for the sentiment module, which uses it to make requests to the HuggingFace service. It updates the configuration files, environment variables, and types to include the HuggingFace API key. It also modifies the tooltip component in the frontend to display the sentiment label instead of the score.
