Merge #13706: doc: Minor improvements to release-process.md

95464c7 doc: Improve command to generate list of authors for release notes (Mitchell Cash)
1c22cc1 doc: Update broken links to now point to gitian-build.py (Mitchell Cash)

Pull request description:

  - Update broken links
  - Improve command to generate list of authors for a release

  ---

  I also note that it asks to ping **wumpus** on IRC, to assist in generating a list of merged pulls and sort them into categories based on labels. I tried to turn this into a simple one-liner as well (something like ``git log --merges --format="- \`%h\` %s (%an)" v0.16.0..v0.16.1``), but it didn't seem to capture everything I needed.

  Would it be worthwhile **wumpus** open-sourcing his code into `contrib/devtools` so there is no single point of failure (even if it can manually be worked around).
