fix how bin tools sort

We set LC_ALL=C when sorting in a bin tool.  This was done
to make the result of using `sort(1)` consistent.

Improved how the Primary files and Secondary files are
sorted by `bin/output-index-inventory.sh` to sort
with "-u -k 1n -k 3.2d".

The above will change `index.html` files for all entries.

Changed `bin/chk-entry.sh` VERSION from "1.1.2 2024-03-17"
to "1.1.3 2024-03-18".

Changed `bin/gen-authors.sh` VERSION from "1.3 2024-03-04"
to "1.3.1 2024-03-18".

Changed `bin/gen-location.sh` VERSION from "1.1 2024-03-04"
to "1.1.1 2024-03-18".

Changed `bin/gen-sitemap.sh` VERSION from "1.3 2024-03-16"
to "1.3.1 2024-03-18".

Changed `bin/output-index-inventory.sh` VERSION from "1.2 2024-02-27"
to "1.2.1 2024-03-18".

Changed `bin/pandoc-wrapper.sh` VERSION from "1.5 2024-03-18"
to "1.5.1 2024-03-18".

Changed `bin/sort.gitignore.sh` VERSION from "1.1.1 2024-02-23"
to "1.1.2 2024-03-18".

Changed `bin/tar-all.sh` VERSION from "1.1 2024-02-27"
to "1.1.1 2024-03-18".

Changed `bin/tar-year.sh` VERSION from "1.1 2024-02-27"
to "1.1.1 2024-03-18".

Performed `make www` to update all entry `index.html` files.
