Update pull request template

This changeset updates our pull request template to be much more streamlined and shifts most of the information to our documentation.  The PR template now links to the docs for folks who are new and unfamiliar with what we require in our pull requests so that the template itself just has the headings and quick outlines to get started more easily and quickly.

+* [ ] TODO item ...
 
 ## Security Considerations
 
-Please think about the security compliance aspect of your changes and what the
-potential impacts might be.
-
-**NOTE:  Please be mindful of sharing sensitive information here!  If you're not
-sure of what to write, please ask the team first before writing anything here.**
-
-Relevant details could include (and are not limited to) the following:
-
-- Handling secrets/credential management (or specifically calling out that there
-  is nothing to handle)
-- Any adjustments to the flow of data in and out the system, or even within it
-- Connecting or disconnecting any external services to the application
-- Handling of any sensitive information, such as PII
-- Handling of information within log statements or other application monitoring
-  services/hooks
-- The inclusion of a new external dependency or the removal of an existing one
-- ... (anything else relevant from a security compliance perspective)
-
-There are some cases where there are no security considerations to be had, e.g.,
-updating our documentation with publicly available information.  In those cases
-it is fine to simply put something like this:
-
-- None; this is a documentation update with publicly available information.
+* Consideration 1
+* Consideration 2
