[Feature Request] Make field required in resulting schema, but optional in DB

[CyanoFresh]

Is your feature request related to a problem? Please describe.
Add ability to mark field "required", even if it is optional in prisma schema (with ? mark)

model Model {
fieldA Int? /// @zod.custom.use(z.number().int().positive())
}

results in:

fieldA: z.number().int().positive().nullish(),

but desired:

fieldA: z.number().int().positive(),

Describe the solution you'd like

• @zod.custom.use() should not implicitly add .optional() or .nullish() to the end of type
• @zod.[...].required() will not make this field nullish

Describe alternatives you've considered
Extending a scheme and overwriting this field's type
