Enhancement: modification required in the "Long" description of add subcommand

[kaitou-1412]

It's currently `Add (cobra add) will create a new command, with a license and
the appropriate structure for a Cobra-based CLI application,
and register it to its parent (default rootCmd).

If you want your command to be public, pass in the command name
with an initial uppercase letter.

Example: cobra add server -> resulting in a new cmd/server.go`

This needs to be modified according to "cobra-cli" i.e. cobra add server -> cobra-cli add server
Similar changes are required everywhere.
