Installation issues on Databricks

[lukasz-kastelik]

Describe the bug
I am trying to run a simple pipeline on Databricks ML runtime 14.3 LTS
I installed haystack using pip install haystack-ai and during import:
from haystack.components.embedders import SentenceTransformersDocumentEmbedder

Error message
ImportError: cannot import name 'Iterator' from 'typing_extensions' (/databricks/python/lib/python3.10/site-packages/typing_extensions.py)
File , line 12
10 from haystack.components.retrievers.in_memory import InMemoryEmbeddingRetriever
11 from haystack import Document
---> 12 from haystack.components.embedders import SentenceTransformersDocumentEmbedder

Expected behavior
Import works just fine

Additional context
No preprocessing was done.

To Reproduce
Create a databricks cluster with 14.3 ML LTS runtime, use default configuration, run pip install haystack-ai
