[sjrl]

Related Issues

• fixes failing typing tests

Proposed Changes:

Update experimental Agent to also take in generation_kwargs that was added in this PR deepset-ai/haystack#9616 and released in Haystack 2.20.

The changes were made in such a way that both Haystack 2.19 and 2.20 should work with this version of experimental Agent.

How did you test it?

Tested using integration tests locally on version Haystack 2.20 and Haystack 2.19.0
