Timedelta cannot be used in match statements

Bug report

Bug description:

Timedelta cannot be evaluated in match statements, see example below

from datetime import timedelta

td = timedelta(hours=1)

print(td == timedelta(hours=1)) # evaluates to True

match td:
    case timedelta(days=1):
        print('day')
    case timedelta(hours=1):
        print('hour')
    case _:
        print('unhandled') # prints `unhandled`

CPython versions tested on:

3.11

首先，在 CPython 3.11 上复现所提供的 timedelta match 语句，并将其行为与相等性进行比较。该 issue 没有指出源文件或测试入口点，因此请追踪类模式如何处理 timedelta 属性，并在确定合适的回归测试之前，确定预期的匹配行为。
