site: remove CLI auto-generated docs prior to generate

Otherwise we can leave behind stale generated files from previous
instances of the site configuration.

Do not remove the cache files, because otherwise on a
Preprocessor-No-Write-Cache they will not get added back, a change that
would, ironically, create noise in a commit where we are intending there
to be less noise.
