Bug 27114: Use Template Toolkit plugin for Koha plugins hook 'intranet_catalog_biblio_tab'

Koha plugins hook 'intranet_catalog_biblio_tab' is for a template,
it will be better it uses Template Toolkit plugin like intranet_js, ...
It will allow using it in other places like MARC details page for example.

Test plan uses a plugin from git.biblibre.com because this hook is not
yet in KitchenSink.

Test plan :
1) Enable Koha plugins
2) Download and install the latest version of this plugin
https://git.biblibre.com/biblibre/koha-plugin-intranet-detail-hook
3) Browse to catalogue/detail.pl for a record
4) Note you see two new tabs with content
