These two functions in hermes_cli/profiles.py have no callers — the live
`hermes completion {bash,zsh}` command uses hermes_cli/completion.py's
generate_bash() / generate_zsh() instead. Multiple PRs (incl. #6141) tried
to fix the trailing-`_hermes "$@"` zsh bug here, only to discover the
patch never reached users. Delete the dead code so future contributors
patch the right file.
The actual user-facing fix lives in the preceding cherry-picked commits
to hermes_cli/completion.py.
