Subclassing guide doesn't work?

[dehnert]

It doesn't seem like the subclassing guide works -- by default, Python doesn't inherit decorators from parents (see eg https://stackoverflow.com/questions/3421337/accessing-a-decorator-in-a-parent-class-from-the-child-in-python for discussion of how to make it work), and py-cord doesn't seem to have done the custom work to make it work. The result is that, eg, the @slash_command decorator is undefined in a subclass.

To Reproduce

Copy the first example from https://guide.pycord.dev/popular-topics/subclassing-bots:

$ cat > sample.py
import discord

class MyBot(discord.Bot): # subclass discord.Bot
    async def on_ready(self): # override the on_ready event
        print('Logged in as')
        print(self.user.name)
        print(self.user.id)
        print('------')

    @slash_command() # create a slash command
    async def ping(self, ctx):
        await ctx.respond('Pong!')

bot = MyBot()
bot.run('token')
$ python3 sample.py
Traceback (most recent call last):
  File "sample.py", line 3, in <module>
    class MyBot(discord.Bot): # subclass discord.Bot
  File "sample.py", line 10, in MyBot
    @slash_command() # create a slash command
NameError: name 'slash_command' is not defined

Expected behavior

Bot runs, with a ping slash command defined.
