#3799 [Docs] Update the plugin setup guide Issue created by samhita-alla Description Our existing plugin setup guide provides instructions for the Flyte sandbox environment but does not cover the Flyte demo cluster. To address this issue, we need to: • Install plugins on the demo cluster. • Enhance the plugin setup guide by incorporating detailed, user-friendly instructions that are more explicit and comprehensive in nature. Key points to ponder: • Can plugins be installed on the demo cluster? • Is the web API plugins guide necessary in light of Flyte agents' functionality?
