🆕 feat(utils.py): add function to remove API keys from flow data

This commit adds a new function called `remove_api_keys` to the `utils.py` file. The function takes in a dictionary representing a flow and removes any API keys from the flow data. The function iterates through each node in the flow and checks if the node contains any API keys. If an API key is found, the function sets the value of the key to `None`. This function is useful for removing sensitive information from flow data before it is stored or transmitted.
