Text of policies

This is the text of the first policy:

> As stated in our privacy policy, "We do not want to need your data", and this also holds for the use of our user and project data for using or training generative "AI": The Codeberg forge and its associated services are not and will not use the code or data of projects and users to train "Artificial Intelligence" tools such as Large Language Models, whose purpose is to create output modelled after their training input. As an association, we believe that these technologies are incompatible with responsibly creating and maintaining free & open source software.

And the second, added to the site's terms of use:

> You must not share projects that mostly consist of code written by "generative AI"-tools (including services such as *Claude*, *OpenAI Codex*). Such projects having an unclear copyright status (see requirements § 2 (1) 1 and § 2 (1) 3) and furthermore have little safeguards to ensure that they do not include harmful code (c.f. § 2 (1) 5).
