Workflows reference: event.params should be event.payload

[FredKSchott]

Multiple files in the workflows reference use event.params to access workflow event data, but the actual WorkflowEvent<T> type from cloudflare:workers uses event.payload.

From the runtime type definition:

export type WorkflowEvent<T> = {
    payload: Readonly<T>;
    timestamp: Date;
    instanceId: string;
};

Affected files (non-exhaustive):

• references/workflows/api.md — e.g. event.params.paymentMethod, event.params.userId
• references/workflows/patterns.md — e.g. event.params.imageKey, event.params.email, event.params.sourceUrl
• references/workflows/gotchas.md — best practices mention event.payload in one place but the rest of the docs consistently use event.params

All instances of event.params in workflow code examples should be event.payload.
