Prepare rbmotd 3 for release.
Review Request #14358 — Created Feb. 27, 2025 and submitted — Latest diff uploaded
This adds a new README for rbmotd and updates the package information
for the new requirements for Review Board 7.We ideally would be using pyproject.toml, but the support for
pyproject-based extension packages depends on the in-development
Review Board 7.1.
Checked the README rendering. Tested links and spelling.
Tested building new packages.
