Add link to how to add new release-monitoring entries

[ermo]

tarkah do we have tooling to parse monitoring.yml and notify of any new releases? It's cool zellij is in the release-monitoring.org database

ReillyBrogan I'd note that if you create a login on release-monitoring you can add projects there that aren't already monitored. It's pretty easy I've added several projects to it They have their own documentation It's different for each package source
