cache html responses

[MiniDigger]

right now we have a cache rate of 0% at cf for content pages because they set a cache control max age of 0
we should set it to something sensible, like at least an hour.
I didnt find anything on how to do this with starlight, which is pretty embarrassing, maybe we need to do it at CF

starlight doesn't serve anything, so it doesn't control the headers

you probably want to do this in the public/_headers file

[zlataovce]

but also is there a measurable difference between pages serving it and the cache serving it? it's a static site and they should be both running at cloudflare's edge
