Replace mentions of Review Board 7.1 with 8.0 in the docs.
Review Request #15006 — Created April 7, 2026 and submitted — Latest diff uploaded
We decided to release a Review Board 8.0 instead of a 7.1. This change replaces any mentions of 7.1 with 8.0. This only involves documentation and code comments, as we already had a change that updated the actual code for the version renaming.
Ran unit tests.
