fix(ollama): Fix handling message content lists (#32881)

Browse Source 
The Ollama chat model adapter does not support all of the possible
message content formats. That leads to Ollama model adapter crashing on
some messages from different models (e.g. Gemini 2.5 Flash).

These changes should fix one known scenario - when `content` is a list
containing a string.
