WebRetriever with GoogleAPI not working

[bilgeyucel]

Describe the bug
WebRetriever doesn't work with GoogleAPI when I provide engine_id through search_engine_kwargs

Error message

...
TypeError: WebRetriever.__init__() got an unexpected keyword argument 'search_engine_kwargs'

Expected behavior
Error message says that WebRetriever has no init argument but it has.

@bilgeyucel it would be great if you could check if the PR solved this issue (by installing Haystack from main).

Hi @anakin87, it seems like the main issue is solved with on the main branch, thank you for the information 🙌
However, the issue mentioned in #6003 Exception: Exception while running node 'Shaper': 'score'
Enable debug logging to see the data that was passed when the pipeline failed persists. So, I'll close this one but add that info to #6003.
