fix: Run update_embeddings in examples

[nickprock]

Proposed Changes:

• Added document_store.update_embeddings to example pipelines for faq and hybrid faq
• Skip PromptNode tests with external providers if API_KEY is not set. Previously, if you had no HUGGINGFACE_API_KEY set and then run test_getting_started , before this PR you would download falcon-7b-instruct.
• Delete document indices after example pipelines ran. Otherwise faq pipeline reuses the document index from the qa example pipeline
• Rename document index to example-document. Otherwise by running the example, users might delete their default index document with their own data
• Install fewer dependencies, for example weaviate is not installed in the workflow because it's not needed, etc.
• pylint no-logging-basicconfig check is disabled in examples
• imports are sorted in examples
• anthropic was missing in test_getting_started parameterized test

How did you test it?

manual verification, CI

Hi @nickprock Thanks for adding this fix and I see you already merged Haystack main just now. Before, the PR was still based on the version of July. 👍
Let's change the release notes so that the PR note is listed under fixes. We use upgrade for breaking changes with guidelines how to upgrade. Something like Added documents_store.update_embeddings to hybrid search example pipeline. under fixes would be great!

@nickprock In the failing test you see that we also updated precommit hooks since last time.
pre-commit install should do the trick before committing. More details here: https://github.com/deepset-ai/haystack/blob/main/CONTRIBUTING.md#installation
Just let me know if you need help. 🖖
