Update beginner function execution tutorial as the expected data has changed

[uzarnom]

The curl command's body now requires the following:

-d '{"body":"this is json data"}' # new
-d '{"data":"this is json data"}' # previous

Which translates to the following in javascript fetch. (This took me 2 days to figure out, I am such an idiot)

fetch('https://64d4d22db370ae41a32e.appwrite.global', {
  method: 'POST',
  headers: {
    'X-Custom-Header': '123',
    'x-appwrite-user-jwt': '<YOUR_JWT_KEY>',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    'body': 'this is json data'
  })
});

What does this PR do?

Update the beginner function execution tutorial so the curl command contains the correct data.

Test Plan

I tested it against: https://syd.cloud.appwrite.io/v1 - REST

my javascript code is:

const payload = JSON.stringify({
        'user': l_user,
        'message': l_message
    });
    
    var bodyString = JSON.stringify({
        body: payload
    });

    var request = {
        method: 'POST',
        headers: {
            'Content-Type': 'application/json',
            'X-Appwrite-Project': PROJECT_ID,
            'X-Appwrite-JWT': jwt 
        },
        body: bodyString
    }

I have not looked, but it seems to be well documented somewhere as I found the answer somewhere in solved git issues, and in Discord archived messages.

I have read the CONTRIBUTING.md, but I am an really stupid (also sick and sleepy).

Walkthrough

This pull request updates documentation in the products functions execute page. A curl example was modified to send the function body under the "body" field instead of "data" in the POST payload. Additionally, a trailing newline was added to the Permissions documentation section for file formatting consistency. No exported entities or code logic were altered.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~8 minutes

• The curl example field change ("data" to "body") requires verification that the API endpoint correctly accepts the "body" field for function body parameters
• Documentation-only changes with minimal scope and straightforward nature
• Consider confirming the API specification aligns with the updated curl example parameter
