[FEATURE] Create dynamic help commands

[anf]

Is your feature request related to a problem? Please describe.
In BotANF v1, the help command was almost fully hard coded which is not very good to maintain and code-quality was very low.

Describe the solution you'd like
The help command be as dynamic as it could.

Additional context

• The command sorting should be handled
• The commands per embed displayed should be handled
• The command categories should be handled
• Hidden commands should not be displayed
• Descriptions should be shown alongside
• A special help command i.e help <command name> should be set up the same way.

[tomlin7]

commands should be sorted based on roles or permissions

example:

when a normal member uses help command, only the commands available for their use should be displayed

when an admin uses help command, all the mod/management commands (can be a category) should also be displayed
