Dynamic views for command help embeds (#1939)

Dynamic views for command help embeds

Adds views for commands to navigate groups.
For subcommands, a button is added to show the parent's help embed.
For groups, buttons are added for each subcommand to show their help embeds.

The views are not generated when help is invoked in the context of an error.
