Remove restriction python<3.13 in pyproject.toml

[softwareentrepreneer]

Is it possible to remove the restriction <3.13 in pyproject.toml:
requires-python = ">=3.8,<3.13"

My local project has python="^3.10", so now I am not able to install haystack-ai with version 2.9.0 because of this restriction.
This restriction didn't exist in version 2.7.0

Hello!

This restriction was introduced in #8547 because of incompatibilities with 3.13.
We should reevaluate this and do some testing.

That said, Haystack is currently compatible with 3.8, 3.9, 3.10, 3.11, and 3.12.
So I think you can find a workaround to make it work for you.

I reopened this issue because at some point we should provide compatibility with 3.13
