Pr #1271 removes duckduckgo-search from base packages, thus requiring users to install a specific set of dependencies to run it: this means many basic examples require a specific packages, which is a bit of friction. To remove this friction, maybe it's possible to enable the DuckDuckGoSearchTool without requiring `duckduckgo-search, for instance taking elements from this function: https://github.com/deedy5/duckduckgo_search/blob/b39a1565972b94e8c0b87e63c833f7ca4f3743e6/duckduckgo_search/duckduckgo_search.py#L254.
