Emoji regex is not supported in some environments

[jacoblee93]

Unicode regexes are not supported in all environments - React Native in particular. One is used here:

https://github.com/StefanTerdell/zod-to-json-schema/blob/master/src/parsers/string.ts#L26

This is problematic because even if we don't use a schema containing z.string().emoji(), the regex is instantiated immediately as the object is imported. The fix in Zod was to lazily instantiate the regex:

colinhacks/zod@9340fd5

With this, the rest of the library is usable in such environments (though .emoji() still won't be).

I'll open a PR with a similar fix.
