Support Python 3.13 (#2844)

* ci: support python 3.13 on CI

* docs: update docs about support python version

* build: adds requires python <3.14

* build: explicit tokenizers dependency

Added explicit tokenizers dependency: Added tokenizers>=0.20.3 to ensure a version compatible with Python 3.13 is used.

* build: drop fastembed is not longer used

* build: attempt to build PyTorch on Python 3.13

* feat: upgrade fastavro, pyarrow and lancedb

* build: ensure tiktoken greather than 0.8.0 due Python 3.13 compatibility
