Update the help slash command

[sinsniwal]

The Slash command structure is built; only the embed requires changes portion that needs editing: iitm-server-bot/cogs/slash.py help function.

Requirement: List the commands that are not hidden.

Why not use the built-in help command?
Since hybrid commands are a thing, you can just invoke the help command by creating a context using Context.from_interaction

Customizing the help command is a more manageable task than maintaining a list of usable commands per user.

What are your thoughts?

Why not use the built-in help command?

@sloth-ontabasco wanted it to be interactive
with buttons & pagination

Which is possible with the built in HelpCommand.
