'Reverse List' does not return any values in the Variables - Lists examples

The example 2_Lists.robot in the Variables in the "Getting started" section contains a mistake, see https://robotframework.org/?tab=0&example=Variables#getting-started

Incorrect example:

Test with some Collections keywords
    ${list}=    Create List    1    2    3
    Append To List    ${list}    4    5    6
    ${list2}=    Create List    7    8    9
    ${new_list}=    Combine Lists    ${list}    ${list2}
    ${reversed}=    Reverse List    ${new_list}
    Log To Console    ${reversed}

The keyword Combine Lists does not return any values, but only affects to the variable given to the keyword. As a result, the last line will log a None value.

Correction:

    Reverse List    ${new_list}
    Log To Console    The reversed list: ${new_list}

打开 Variables 的“Getting started”示例 2_Lists.robot，并将 Combine Lists/Reverse List 行与 issue 进行比较。更新示例，使 Reverse List 操作 new_list，并让控制台记录该列表，然后验证渲染后的示例不再打印 None。
