fix(help): bypass any cat alias/functions in help output

[bezhermoso]

The bat CLI is a very common cat alternative that, among many things like syntax highlighting, provides an auto-paging feature:

alias cat='bat --paging=auto' # OR bat --paging=always

Unfortunately, each invocation of cat can trigger a separate pager session, breaking the help output into fragmented pages.

Fix: Invoke the actually cat binary from $PATH by using command cat, bypassing any aliases or functions.
