Update the displayed documents at https://docs.oasis-open.org/templates/ and .../TChandbook

At the top level of the OASIS Library are directories for each TC (and most OPs), along with a directory "templates".
NOTE: Also, the same issue applies to the directory https://docs.oasis-open.org/TChandbook/
Browsing to either of these directories will redirect the browser to a single document.

The documents need to be updated.
This can be done by updating appropriate files, but only in the "Staging server" directories.
(Using a browser, you will not see these files in the OASIS Library.)

In the staging server, the related directories are:

• /var/www/vhosts/docsdot/htdocs/TChandbook
• same: https://docs-staging.oasis-open.org/TChandbook

• /var/www/vhosts/docsdot/htdocs/templates
• same: https://docs-staging.oasis-open.org/templates

AFTER updating and testing on the staging server, this can be "synced" back to the OASIS Library for public display - similar to other TCs.
