[BUG] Error when giving somebody a role

[ItsShunya]

When you try to give somebody a role (for example welcome role) that is higher than the bot's role, it will display a message.

Confirmed this same error happens on adding reaction roles.

This issue can't be solved but we can add an error handling to display a message when this happens. Problem should be adressed to the server's admin to raise the bot permissions.
