update json wrapper tools

The json wrapper tools, `bin/jfmt-wrapper.sh`, `bin/jprint-wrapper.sh`
and `bin/jval-wrapper.sh` have been updated as follows:

The `-Q` option now does a quick test, ignores args, and exits.
With `-Q`, the required args are ignored and are not required.

The quick testing of `JSONPath.sh` via `-Q` is fixed.

Leading commends about the tools have improved.

A few typos have been fixed.

The `-v 3` variable printing is performed just before any `-N` test.

Changed `bin/jfmt-wrapper.sh` VERSION from "2.0.1 2025-04-21"
to "2.0.2 2025-05-04".

Changed `bin/jprint-wrapper.sh` VERSION from "2.0.1 2025-04-21"
to "2.0.2 2025-05-04".

Changed `bin/jval-wrapper.sh` VERSION from "2.0.1 2025-04-21"
to "2.0.2 2025-05-04".

Updated sitemap.
