Issue 482 fix event display

[mariacha]

What issue(s) does this solve?

• Issue Number: https://github.com/wri/WRIN/issues/482

What is the new behavior?

• Changes a largely-hard-coded DSField for the Add To Calendar button into a field that uses configuration options borrowed from the AddToCalendar widget.
• Creates a Calculated field that just returns whatever value is in the Date/Time field (so I can display the same field twice).

Profile requirements:

• Does deploying this change require a change to config at the site level (choose one)?
  • No config change is required.
  • Yes, and I have written an update hook to apply these config changes.
  • Yes, and I've included updating instructions to be added to the release notes. The next release will need to be a major version increase. (Only do this in special cases.)

Site-level pull requests for testing. Only merge when these PRs are approved:

@mariacha since you are the original creator I can't ask you to code review, but this is assigned to you!

@unclegcb do you have time to make a few more changes here? I found two suggestions, hopefully small

Let's give this a more helpful description:

The event description in the "Add to Calendar" link. Default value is "[node:title] - from WRI: [node:url:absolute]"

(you'll have to html encode the brackets so they look right and can be copy/pasted)

Since we're still using the old-fashioned pantheon commands drush updb then drush cim this new field is getting deleted and re-created post-update. Can you update Distro helper to call the syncUUIDs command right before the config gets auto-exported here? Then open a new branch and we'll test it out on this repo.
