fix: add supportsOptionalClassProperties to TypeScriptZod target language

[inferrinizzard]

Summary

Added supportsOptionalClassProperties to TypeScriptZodTargetLanguage in order to fix handling of optional properties in JSON Schema that are not listed in required array.

JSON Schema

{
  "properties": {
    "foo": { "type": "string" },           // standard string
    "bar": { "type": ["string", "null"] }, // string | null union
    "baz": { "type": "string" },           // string, optional
    "qux": { "type": ["string", "null"] }, // string | null union, optional
  },
  "required": ["foo", "bar"]
}

Old

export const Schema = z.object({
  foo: z.string(),                               // standard string
  bar: z.union(z.string(), z.null()),            // string | null union
  baz: z.union(z.string(), z.null()).optional(), // string, optional
  qux: z.union(z.string(), z.null()).optional(), // string | null union, optional
})

New

export const Schema = z.object({
  foo: z.string(),                               // standard string
  bar: z.union(z.string(), z.null()),            // string | null union
  baz: z.string().optional(),                    // string, optional
  qux: z.union(z.string(), z.null()).optional(), // string | null union, optional
})

CI Test failure looks like #2462

[dvdsgl]

Yes, sadly our CI is currently haunted.

[inferrinizzard]

@dvdsgl Are you guys looking for more maintainers? Would like to help out if there's space available

[dvdsgl]

Yes please!

We're getting desperate: https://replit.com/bounties/@dvdsgl/fix-our-oss-project

Want to see if you can fix CI? I'll pay you the bounty.

Hello. I believe this PR should fix #2462. The failing tests are now passing locally for me on that branch.

[inferrinizzard]

@dvdsgl great to hear that the CI issue has finally been fixed - is there a link to the maintainer slack (or is that defunct?) Would like to chat to some folks to see which areas of the codebase need more effort before jumping on fixing more issues.

We don't have a discourse or slack anymore, but we could make a WhatsApp thingy for now: https://chat.whatsapp.com/E3Heqe9Tjl8IBVqpeFMyPp
