1.15 minor releases highlights

Heads up: To prevent a cognitive name collision with LLM Agents, Flyte Agents are being renamed to Connectors. This is a WIP and no user-level changes are expected. We'll keep you posted.

• Webhook Connector: easily send workflow notifications using webhooks. No more email queues! https://github.com/flyteorg/flytekit/pull/3058
• Simplified interface for declaring Resources, including support for tuple/list and stricter validations https://github.com/flyteorg/flytekit/pull/3177
• Customize the Spark Driver and/or Executor Pod specs using PodTemplates! https://github.com/flyteorg/flytekit/pull/3016
• Both the FileSensor and BaseSensor now support timeout, preventing the Connector from waiting indefinitely for a condition to be met https://github.com/flyteorg/flytekit/pull/2745
