Hello,

I’m using sphinx-proof version 0.2.1 with Jupyter Book and have set the localization to Italian via the _config.yml file as follows:

sphinx:
  config:
    language: it
  extra_extensions:
    - sphinx_proof

However, despite this configuration, the theorem environment labels (Definition, Theorem, etc.) still appear in English rather than Italian (e.g., Definition instead of Definizione).

Everything else seems to work fine, but it appears the localization for these labels is not applied correctly when used inside Jupyter Book.

Is this a known limitation or is there a recommended way to enable the Italian localization for theorem labels in this setup?

Thanks for your help!
