feat: Disable Gradio Analytics (#1165)

* Disable Gradio Analytics

Gradio analytics can be disabled by either using the kwargs `enable_analytics` on `gr.Blocks`, or by setting the env variable `GRADIO_ANALYTICS_ENABLED` to something different from `True`.

Since that Gradio does not seem to respect their code contract (around `enable_analytics`), and that they are performing other operations only based on the value of `GRADIO_ANALYTICS_ENABLED` (c.f. `gradio.strings` https://github.com/gradio-app/gradio/blob/main/gradio/strings.py#L39), we are disabling gradio analytics by setting the required env variable to `False`.

Note: Setting an environment variables using `os.environ['foo'] = 'bar'` on system that are not based on unix might not work.

c.f. https://docs.python.org/3/library/os.html#os.environ for details on how `os.environ` works and all its caveats
