While using the AI API Explorer module, a PHP warning is triggered when provider configuration values contain arrays.

Error:
Warning: Array to string conversion in Drupal\ai_api_explorer\AiApiExplorerPluginBase->addProviderCodeExample()

Cause:
In AiApiExplorerPluginBase::addProviderCodeExample(), the code assumes non-string values can be directly concatenated into a string. However, when $value is an array, PHP throws an "Array to string conversion" warning.

Steps to Reproduce

  1. Go to this path /admin/config/ai/explorers/chat_generator
  2. Provide some chat message
  3. Click Ask AI button
