Make help menu interactions exclusive to the command author

Currently, everyone can control the help menu using the buttons. We need to make sure that only the command author should be able to interact with the buttons to change the pages of the help menu.
Make necessary changes in utils/helper.py.

Make sure to read and follow Contributing Guidelines.

Embedded message in command_not_found and subcommand_not_found

# ./utils/helper.py

    async def subcommand_not_found(self, command: commands.Command, string: str, /) -> None:
        if isinstance(command, commands.Group) and len(command.all_commands) > 0:
            error_message = f"**Error 404**: Command `{command.qualified_name}` has no subcommand named `{string}`!\n"
            error_message += f"\nAvailable subcommands:\n`{'`, `'.join(command.all_commands.keys())}`"
        else: 
            error_message =  f"**Error 404**: Command `{command.qualified_name}` has no subcommands!"
        channel = self.get_destination()
        await channel.send(embed=Embed(description=error_message))

Using the above subcommand_not_found function to handle subcommand not found raises discord.ext.commands.errors.CommandInvokeError.

Similarly, command_not_found is raising the same error when written in a similar manner, i.e.,

# ./utils/helper.py

    async def command_not_found(self, string: str, /) -> None:
        error_message = f"**Error 404**: Command `{string}` not found!"
        channel = self.get_destination()
        await channel.send(embed=Embed(description=error_message))

Goal: We want to handle this error and send a response with an embedded message.
