该数据库包含以下数据：
[
{id: 1, username: "test", amount: 2},
{id: 2, username: "example", amount: 0},
{id: 3, username: "hello", amount: 1},
{id: 4, username: "fsa", amount: 0},
{id: 5, username: "aas", amount: 10},
]
现在我需要使用 typeorm 查询来检索数据，但我需要根据 amount 字段对其进行排序，并且限制只有 3 个用户，所以我应该得到这个：
[
{id: 5, username: "aas", amount: 10},
{id: 1, username: "test", amount: 2},
{id: 3, username: "hello", amount: 1},
]
如何进行该查询？
