🚀 Enhancement: Simplify the set time requirements for scheduling an SMS on Appwrite Messages

### 🔖 Enhancement description Remove the requirement to match the exact second with 60-second differences from when a scheduled time is created. ### 🎤 Pitch **Presently:** - Using Appwrite Messaging, a user can set the time they want an SMS to be sent by date (MM/DD/YYYY) and time (HH:MM:SS) - Unless they match the exact second that they created the scheduled time with the time they wanted the SMS to be sent, they will receive an error message with suggested correct values.  **Why this should be implemented:** - It seems highly unlikely that users will ever set the correct time without checking a clock's time down to the second. **How it would be used:** - Users can schedule their SMS more easily by removing the seconds and changing the step to 1 unit. - <img width="765" alt="Discord reply" src="https://github.com/appwrite/appwrite/assets/56854081/d0d4c64b-7924-4db8-805a-fb8f3657caba"> ### 👀 Have you spent some time to check if this issue has been raised before? - [X] I checked and didn't find similar issue ### 🏢 Have you read the Code of Conduct? - [X] I have read the [Code of Conduct](https://github.com/appwrite/.github/blob/main/CODE_OF_CONDUCT.md)
