corrected use of REPO_URL shell variable, added REPO_TOP_URL

The shell variable `$REPO_URL` was often set to
`https://github.com/ioccc-src/temp-test-ioccc/blob/master` which was
not consistent with the variable name.  In some cases the `$REPO_URL`
was used as the top level path for a git repo (w/o the `/blob/master`),
and in most cases was used as a GitHub URL path under which files may
be found (with `/blob/master`).

We change the shell variable `$REPO_URL` to be `$REPO_TOP_URL` and
use the value `https://github.com/ioccc-src/temp-test-ioccc`, w/o
the `/blob/master`, and adjust places where the GitHub URL path (with
`/blob/master`) is needed.  A new shell variable `$REPO_URL` will contain
the `https://github.com/ioccc-src/temp-test-ioccc/blob/master` (with
`/blob/master`).

In tools that use `-u` the option was changed from `repo_url` to
`repo_top_url`.  The `-u repo_top_url` will set the
 `$REPO_TOP_URL` shell variable (w/o the `/blob/master`), and then set
 the variable `$REPO_URL` as `$REPO_TOP_URL//blob/master`.

Fixed a shellcheck issue with `bin/tar-entry.sh`.

Corrected name of shell variable `$AUTHOR_GUTHUB_USERNAME` to be
`$AUTHOR_GITHUB_USERNAME`.

The substitution symbol `%%REPO_URL%%` has used in markdown
files remains as before.  That is, REPO_URL is set according
to the shell variable `$REPO_URL` which includes `/blob/master`).

Fixed broken `author_handle` links in `authors.html`.

NOTE: Except for correcting links `authors.html` as noted above,
no HTML content was modified by these changes.
