Wishlist: related PR review clubs section

[glozow]

For the review clubbies who consume meetings like youtube videos, I wish we had a section at the end of meetings for "related PR review clubs."

I think it's nice to link to other review clubs we've done on the same topic (e.g. Minisketch/Erlay, coin selection, deployments). But it's unmaintainable if it requires the host/someone to remember all past review clubs. I think the best approach would be to (optionally) tag meetings with a topic from a list of topics in the preamble (more specific than the component groupings, perhaps can correspond to optech topics). That way we can tear down with a quick sed script if we change our mind.

Great idea!
