Alternate H.ghci does not work under Ubuntu Linux

[Dominick Samperi]

Describe the bug
Under Ubuntu Linux, H can be started with
stack --nix exec H
But if I modify H/H.ghci and use
stack --nix exec ghci -- -ghci-script H/H.ghci
there is no error message, but H mode is not enabled.
Does not recognize [r|3|], for example.

To Reproduce
Modify H/H.ghci and start H as described above.

Expected behavior
Should start ghci with H capabilities.
Should recognize [r|3|] and not complain there is a syntax error.

Environment
Ubuntu Linux
Version 22.04

Additional context
No problem under Windows using
stack exec ghci -- -ghci-script H/H.ghci
