Fix ThumbnailToImageOnly button

[DOFER998]

The button was fixed, because there was an error in the check, as well as added timeout and disabling the button by time, so as not to burden the bot.

PS. pull requests I was too lazy to do, so I posted here.

class ThumbnailToImageOnly(discord.ui.View):
    def __init__(self, interaction: discord.Interaction):
        super().__init__(timeout=60, disable_on_timeout=True)

            for item in self.children:
                item.disabled = True
            await self.interaction.edit_original_response(view=self)
        except discord.errors.NotFound:
            pass

    async def interaction_check(self, interaction: discord.Interaction) -> bool:
