#20322 fixed the standard `sage` CLI so that if `SAGE_BANNER=bare`, the
simplified, non-unicode banner is displayed.
However, there were several other places this directive was not obeyed.
First `sage --help` would still display the full banner regardless.
Second, the built-in `banner()` function (from what the banner file is
generated) also does not obey `SAGE_BANNER=bare`.
Because there is code that calls `banner()` directly, it should still only
display the simplified banner if the `SAGE_BANNER=bare` variable is set in
the environment (this is particularly relevant in the Docker container on
Windows...)
(This bug caused a live demo to fail! (Mysteriously the same demo did not
fail when I tested it minutes earlier....not sure why it suddenly
changed))
