remove the staging component from the status site
while the staging site is useful for large sites, particularly because it allows a faster "push to prod" for sites that take a while to compile, or that need thorough review before going live, I feel it is not so appropriate here.
the status site needs to be more nimble: updates need to go out quickly and reliably. we often update it as a second thought, in a middle of an emergency. for example, in team#41388 (closed), we performed at least two updates to the site, and the second one (!40 (merged)) is still not pushed to prod at the time of writing, even though @lavamind reviewed it.
whether it was forgotten or is waiting for review is unclear, but i bet it was forgotten. i know i have forgotten to push to prod on some sites. on sites like the blog or the main website, people will notice quickly or another update will relatively quickly correct the situation. but the status site is not updated as frequently, so an update can live in staging for a while before someone notices the mistake.
so: let's remove staging here. concretely, that means that changes will go live to prod when we merge branches to main.
