Find a place for lifecycles page to live in navbar

Per discussion w/ @jennybc & squad, https://www.tidyverse.org/lifecycle/ should probably have a place to live that you can get to without clicking on a lifecycle button…

Same for repo labels

It would also be nice if clicking a lifecycle on that page linked to you all the packages that are in that state.

@jayhesselberth, I think the challenge there would be scope — unless we just did straight up tidyverse organization packages. With usethis, there are packages that have no affiliation with anything tidyverse-related using the lifecycle badges, which is great, but would make it hard to automate based on pingbacks!

There are also r-lib packages to consider— some of which I think would be really useful to have as e.g. examples, but that aren't technically tidyverse…

Maybe something more to the effect of e.g. would be useful.
