org-capture: Update :package-version for org-capture-templates

* lisp/org-capture.el (org-capture-templates): Add package-version
keyword for recent changes, removing the now out of date and
unnecessary version keyword.

This option changed in both d06aa486d (Add in support for filling in
the bare link in org capture, 2020-09-14) and 83c93e6fe
(org-capture.el: Give a default value when prompting for a property,
2020-09-23).
