Add Graduation Semester to email template variables

[StephanieVUGSC]

In Vireo 3 there is a template variable, GRAD_SEMESTER. This is an important and highly used variable that will need to be replicated in the Vireo 4 email templates.

dc.date.created is listed in the template variable FIELDS section but the value is outputs is not in the required format. Example: 2019-12-01T06:00:00.000Z The example is from submission 4 in test-etd.org, March 29 Action log.

This issue is also related to #1162

Clarification. Both dc.date.created AND dc.date.issued should map to the Graduation Semester. dc.date created is expressed in YYYY-MM format and dc.date.issued is expressed in natural language such as May 2019.

We would propose to address this simply by formatting all date field values in a human readable way for email templates. The team calls this a 2 pointer to do it in such a way.

Please confirm that an example of a "human readable way" is "May 2019".

@StephanieVUGSC yes, "human readable way" is intended to mean "May 2019".

This might be resolved with the recent date/time fixes in pull request #1683 .

As of 4.2.6, there is still no GRAD_SEMESTER template variable in the email template modals.
