fix[zod]: enable multiple properties of array consts

[sirtimbly]

Status

READY

Description

This should fix #1027. The zod function that concatenated consts while parsing the properties of schemas was able to handle multiple properties (eg. min:2, max:5) only on objects, but not arrays. This code checks if there are multiple consts and concatenates them intelligently depending on it being either a single string or an array of strings.

1. Look at the file `tests/generated/zod/nestedArrays.ts
2. The file should not contain any extra commas that cause a typescript parsing error.
