Allow apostrophe in email validation

[seanmacisaac]

Also add tests for apostrophe for both cases since the regex is different for the last character.

Not sure if the deno files are supposed to be checked in or not (since they are generated) but since they are also include them in this PR.

Fixes at least the most recent comments in #2396

Would love for this to get merged as this is a need for one of our clients, what is needed for this to get merged?

I'm not particularly interested in updating the email regex. #2157 represents a "final rule" on that question.

Zod implements the "gmail standard" now, which I think is the most useful and expected for the average (Latin-alphabet-using) developer. Everything else can use .regex() to customize. In Zod 4 I'm planning to export some common regexes from zod/regex to make it easier for users who are looking to validate against a particular RFC standard.

Apologies, there's no pleasing everyone here and imo this is the best tradeoff.

Adding a solution that I used based on @colinhacks comment so other people can solve this if they find this issue. I modified the Zod email regexp from

zod/deno/lib/types.ts

Line 567 in 76c8ace

const emailRegex =

to allow apostrophes.

 email: z
    .string()
    .regex(
      /^(?!\.)(?!.*\.\.)([A-Z0-9_'+-\.]*)[A-Z0-9_'+-]@([A-Z0-9][A-Z0-9\-]*\.)+[A-Z]{2,}$/i,
      'Invalid email',
    ),

[Update] It appears single quotes are specifically allowed by Google Workspace, just not by regular Gmail. That also appears to be virtually the only difference between the two. So I'm happy to merge this.
