[BUG] Champion Mastery V4 docs might be outdated

[katarem]

Bug Description
Variable chestGranted is missing on the response JSON body.

Problem Description

As you can check in the image, the docs describe that the response body should return the variable chestGranted, but I don't know if A) the docs are outdated or B) it isn't returning the available chest.

Expected Result
As I explained in the Problem Description, it either can be outdated docs or outdated response body on the REST API. It depends on what is actually the problem, the expected should or shouldn't include chestGranted in the response body and docs.

Actual Result
The docs say the Response Body comes with a variable called chestGranted but it is returning a response body without it. But I can't guess if the docs are outdated or the response body.

Developer Impact
Describe how this affects you as a developer. Please include the frequency and severity of the issue.

• Frequency: Happens every call to the champion mastery endpoints
• Severity: When it happens, my library returns null on chestGranted, which is bad for my users if they use Mastery object it will always point to a null.
• Cost: It doesn't cost me anything as it is only a library for Java.
• Efficiency: Requires me to hardcode the chestGranted variable on my code.

Player Impact
This bug doesn't affect League of Legends directly.

Preconditions
There aren't any preconditions.
