[Feature] Validate event data against zod schema

[elbalexandre]

Is your feature request related to a problem? Please describe.
Event data is not validated against Zod schemas used for defining Inngest client event schemas.

Describe the solution you'd like
When Zod schemas are used, the send() function should validate the provided data against the corresponding Zod schema.

Describe alternatives you've considered
An alternative could be to remove EventSchemas.fromZod. This might be less ambiguous, as users familiar with Zod know they can use z.infer.
