Create Dataset: email validation does not match validation in the Dataverse API

[ekraffmiller]

What steps does it take to reproduce the issue?
Go to Create Dataset form, in Point of Contact email, enter an email address that ends with a non-tld string, for example, 'ellen@test.e' and all the other required fields

• When does this issue occur?
  When submitting Create Dataset form
• Which page(s) does it occur on?
  Create Dataset
• What happens?
  It shows an Alert message about a validation error, but it doesn't say what the error is, and the email field isn't highlighted

In the Network tab, the create fails with 403 and this error message:

{
    "status": "ERROR",
    "message": "Validation Failed: Point of Contact E-mail ellen@test.e  is not a valid email address. (Invalid value:edu.harvard.iq.dataverse.DatasetFieldValueValue[ id=null ]).java.util.stream.ReferencePipeline$3@626c7975"
}

Just a couple details from Slack:

• On the backend we use https://github.com/apache/commons-validator
• Perhaps .e is rejected because it isn't a valid TLD according to https://en.wikipedia.org/wiki/List_of_Internet_top-level_domains or http://www.iana.org/domains/root/db

Waiting for Dynamic Multiple Fields PR to be merged.
In the above-mentioned pr, there are some changes and refactor that could be better to wait until keep working on this issue to avoid lots of merging conflicts.
