Zod: Add Configurable Option to Include { offset: true } in Zod Datetime Generation

[OH2015]

What are the steps to reproduce this issue?

1.Generate Zod schemas using Orval with an OpenAPI specification.
2.Observe the generated schema for datetime fields.
3.Notice that datetime fields are defined as datetime() without { offset: true }.

What happens?

The generated Zod schemas have datetime fields defined as datetime() by default, which does not include the { offset: true } option.

What were you expecting to happen?

I expected the generated Zod schemas to include an option to automatically set { offset: true } for datetime fields based on configuration, allowing for proper handling of date-time values without manual modifications.

Any logs, error output, etc?

No specific error output, but the lack of { offset: true } in the datetime definitions leads to potential issues in date handling.
For example, when receiving data like "2024-01-01T00:00:00+09:00", the generated Zod schema cannot correctly interpret the timezone offset, which may result in incorrect date handling in the application.
