OEMetaBuilder: Add links to the metadata schema

Description of the issue

Currently when using the OEMetaBuilder, if a term is unclear or more guidance is needed to fill out a field, the best solution is to go directly to the OEMetadata schema, which has more detailed term definitions as well as examples of what the content of a field should look like.

There are also instances where the field instructions direct the user to visit a different website for information. Specifically, in the "Licenses" section, under "Instruction" the informational text says "A short description of rights and restrictions. The use of tl;drLegal is recommended." No indication is given here that tl;drLegal is a different website that the user should visit to get more info; the metadata schema does provide a link to the tl;drLegal website, but the OEMetaBuilder form does not.

Ideas of solution

Add links in the OEMetaBuilder so that a user can click on a field name to pull up the field's definition in the metadata schema. Also, add a link to tl;drLegal directly in the form.
