If there is an existing translation and its Mermaid diagram is in sync with the Mermaid diagram in the English source, except a few translated words, then use the Mermaid diagram of the existing translation.

Adding this feature was a big effort with the main objective of making it easier for the few applications still stuck in Pydantic v1 to migrate to Pydantic v2.

And with this, support for **Pydantic v1 is now deprecated** and will be **removed** from FastAPI in a future version soon.
