GPT example should not need OPENAI_API_KEY at export time.

[jackie-pc]

openai.OpenAIError: The api_key client option must be set either by passing api_key to the client or by setting the OPENAI_API_KEY environment variable

Solution is probably just to defer client instantiation by one function call.

reflex-examples/gpt/gpt/gpt.py

Line 11 in cb3e32c

client = OpenAI()

to become

def get_client():
    return OpenAI()

We just set something for that var during CI:

reflex-examples/.github/workflows/check_export.yml

Line 63 in cb3e32c

export OPENAI_API_KEY="dummy"

Maybe we should update these examples to use the function-wrapper workaround?

[jackie-pc]

Agree we should update examples.
