[Framework] Bump version of fetch-filecache-for-crawling

The new version follows HTTP cache expiration rules and let one control the
expiration behavior more precisely. Note parameters now need to be explicitly
set, the lib no longer reads them from `config.json` (that's a good thing, the
lib shouldn't require the embedding app to use that pattern).
