Cannot install spacy on Python 3.13

[cbornet]

Spacy 3.8.7 is marked as supporting Python 3.13 but in practice it's not possible to use it as it depends on thinc which doesn't support 3.13.

NB: there was an issue for spacy 3.13 but it's now closed and locked so I couldn't comment on it.

How to reproduce the behaviour

With Python 3.13

pip install spacy

Thinc supports Python 3.13 in v8.3.6, but they haven’t published Python 3.13 wheels for versions ≥ 9.

Thinc supports Python 3.13 in v8.3.6, but they haven’t published Python 3.13 wheels for versions ≥ 9.

OK. So this issue would be fixed by just bumping the thinc min dep version to 8.3.6 I guess.
