Schedule releases of CI4

@Avega thanks for bringing this to discussion! I am eager to hear what the community desires. I will say two things up front:

1. The maintainers team just recently closed out a discussion about committing to a more frequent release schedule. This will go into effect immediately (first one supposed to release last weekend but we have a PR that needs resolution first).
2. We will aim for a general frequency rather than a set schedule - there are too few contributors at this point and all us maintainers have other jobs, family, etc, that makes committing to certain dates unfeasible. The best thing you can do as part of the community is resolve the occasional Issue or supply a review of some Pull Requests - *this is not maintainer work, it is for everyone!*

@iRedds I take offense to your suggestion that the team does not care. We are all volunteers who give significant amounts of our time, though, and effort to this project precisely because we care.
