[#1981] Change link to link to all first timer issues

[logical-1985516]

Fixes #1981

Proposed commit message

The link under 'Workflow' section of DG only links to frontend and
backend issues.

Let's link them to all types of first timer issues so that new 
contributors do not miss out on some other types of issues, such as 
DevOps.
