Fix Issue 2139 (large parts of Medley tree not showing up in files.interlisp.org) and more improvements to files.interlisp.org (#2156)

Here is what this PR does:

Fix Issue 2139: (MAKE-INDEX-HTMLS) was not handling pseudohosts correctly and an errant LI pseudohost was causing MAKE-INDEX-HTMLS to terminate early. Adjusted MAKE-INDEX-HTML so it uses psuedohosts only for the top level directory and everything further down in the tree uses the truenames relative to the top-level pseudohost, Results in a MAKE-INDEX-HTMLS run that works in the presence of random pseudohosts and in a collection of index.html files without difficult to understand and out of context references to pseudohosts.

Remove loadups/build directory from all HCFILES runs (on desktop and via github actions)

Added maiko source code and removed maiko lde executables from HCFILES outputs for github actions - thus adding maiko code and removing maiki executables @ files.interlisp.org.

Fixed scripts/clean_hcfiles.sh so that it actually cleans off all of the index.html files - was missing some.

.github/workflow directory was being left out of HCFILES. Put it back it.
