Update supported Python versions to include 3.13, remove 3.8

[JasonWeill]

Problem

Per https://devguide.python.org/versions/, on 2024-10-07, Python 3.13 was officially released, and Python 3.8 is now end of life (EOL). The documentation mentions 3.8 but does not mention 3.12.

Proposed Solution

Test this extension with Python 3.13. Add support for 3.13 and remove 3.8 as a supported Python version.

[krassowski]

I've tried bumping the version on CI to 3.13 in #1029 but it looks like the dependencies are not ready:

Blocked on:

• Python 3.13 support huggingface/tokenizers#1639

[dlqqq]

@krassowski Thank you for documenting your research here! In summary, we need to wait for pyarrow and tokenizers to have Python 3.13 distributions before we can declare Python 3.13 support.

[krassowski]

Yes, though I would personally also wait until the CI passes with tests running on Python 3.13 before declaring support.

[cecilyen]

pyarrow has added support for Python 3.13. https://arrow.apache.org/docs/python/install.html#:~:text=3.13

[cecilyen]

tokenizers just added Python 3.13 support today. huggingface/tokenizers#1665

It looks like PR was merged but there has not been a new release yet?
