[BUG] Slash command with "Attachment" option type gives an error

[UnlucksMcGee]

Describe the bug.

When trying to accept an attachment argument in a slash command, the library gives an error:
AttributeError: 'Attachment' object has no attribute '_client'

List the steps.

Example test script

import interactions

if __name__ == "__main__":
    bot = interactions.Client(token="YOUR_TOKEN_HERE")
    
    @bot.command(
        name="attach",
        description="Some description",
        scope=YOUR_SCOPE_HERE,
        options= [
            interactions.Option(
                name="image",
                description="Attached image",
                type=interactions.OptionType.ATTACHMENT,
                required=True
            )
        ]
    )
    async def attach(ctx: interactions.CommandContext, image: interactions.Attachment):
        await ctx.send("Success")

    bot.start()

What you expected.

I expected the bot to reply with "Success".

What you saw.

Instead, I received this traceback error given from my Python terminal:

What version of the library did you use?
