Introduction of a New Search Engine for HexDocs

The new HexDocs search engine, powered by Typesense, allows users to search across all Erlang and Elixir packages more effectively. Developers can now scope searches to specific packages directly using the command 'mix hex.search', which preselects the exact packages and versions used in a project. This feature is especially beneficial for newcomers unfamiliar with the ecosystem. A new version of ExDoc has also been released, adding support for custom search engines, making it easier for frameworks like Phoenix to provide tailored documentation searches that include relevant dependencies. The implementation of the search engine is fully hosted by Typesense and reflects collaborative efforts from various individuals and organizations within the Elixir community.
