This pull request adds a new feature to the flow editor that allows
users to easily import example flows from the
[logspace-ai/langflow_examples](https://github.com/logspace-ai/langflow_examples)
repository on GitHub. The feature is accessible via the import example
button
Clicking on the "Import Examples" button opens a dialog box that
displays a list of available example flows from the GitHub repository.
Users can select one example to import, and the flow editor will
automatically add the selected flow to the user's current project.
This feature saves users time and effort by providing a convenient way

Additionally, this feature promotes collaboration and community
involvement by encouraging users to contribute their own flows to the
repository for others to use and benefit from.

This function checks if the `llm` attribute of the `langchain_object` is an instance of `OpenAI`, `ChatOpenAI`, `AzureOpenAI`, or `AzureChatOpenAI`. If it is, it sets the
