Proposed Changes:

• update tutorials 36, 43, and 45 for the new serperdev-haystack package: SerperDevWebSearch moved from Haystack core to haystack-core-integrations
• install commands now include serperdev-haystack; imports changed to from haystack_integrations.components.websearch.serperdev import SerperDevWebSearch
• index.toml: added serperdev-haystack to the dependencies of tutorials 36 and 43 so CI installs it

How did you test it?

• ran tutorials 36 and 43 end-to-end locally (nbconvert to Python, like CI) with real OPENAI_API_KEY and SERPERDEV_API_KEY and the new package installed from the integration branch: both completed successfully
• tutorial 45: only a markdown note and a commented-out optional snippet changed; verified the uncommented snippet (ComponentTool + SerperDevWebSearch from the new package) works against the live Serper API (a full run additionally requires a NOTION_API_KEY)

Notes for the reviewer

• serperdev-haystack is released on PyPI but exclude-newer rules in haystack-tutorials prevent the installation until June 15 noon

The tutorials were not run properly, because of the exclude-newer config. We're discussing excluding the core integrations to avoid that in the future.
