Should clean_site() also delete the cache?

Might help with intermittent cache-related issues.

See relevant work in now closed #2715

It doesn't feel quite right to me since the cache isn't associated with a specific package. Maybe it's worth having a separate clean_cache() function?

Just FYI I ran into some sort of cache issue after upgrading to the latest pkgdown locally. Kept running into a callr error for readRDS(path) that I couldn't clear. After I came across clean_cache(), clearing the cache fixed things. Thanks @jayhesselberth. Posting as it might be useful for others with the same problem.

@shikokuchuo I think you were a victim of #2696

FWIW the version of httr2 that should fixe this is now on CRAN.
