Remove max validation when format is binary

[darkbasic]

{
  type: 'string',
  format: 'binary',
  contentMediaType: 'application/octet-stream',
  maxLength: 20480
}

 const StoreChecklistTemplateRequest = z
-  .object({ description: z.string().max(255), file: z.instanceof(File).max(10240) })
+  .object({ description: z.string().max(255), file: z.instanceof(File) })
   .passthrough()

When there is a maxLength prop openapi-zod-client automatically adds the max operator to ensure the number of characters is appropriate. Unfortunately this won't generate valid zod code whenever the format is of type binary because max is not a valid method for File (Property 'max' does not exist on type 'ZodType<File, ZodTypeDef, File>').

This patch conditionally removes max for binary formats.

I thought about changing it with something like the following:

`.refine(file => file.size <= ${schema.maxLength} * 1024, {
  message: "File must be smaller than ${schema.maxLength}KB",
})`

but I'm not sure whether the openapi specs means bytes, KB, characters or what else whenever you specify maxLength in a binary format.

I've added a regression test to prevent future occurrences.
