[Docs]: Lucia Email and Password Guide Imports

[ericlesslie]

Description

The some of docs branching from email and password use the following import:

import { isWithinExpiration } from "oslo";

Specifically, the out of date documentation is on email verification codes and email verification links. The correct export is named isWithinExpirationDate as shown in password reset.

import { isWithinExpirationDate } from "oslo";

I'm fairly certain it's a drop in replacement, since the code for isWithinExpirationDate on the oslo package is,

export function isWithinExpirationDate(date) {
    return Date.now() < date.getTime();
}
