ActiveStorage::Blob and others excluded from Docs

[mvastola]

The rails repository's .yardopts file limits documentation to files matching act*/lib/**/*.rb and railties/lib/**/*.rb.

However, there are several files vital to activestorage that reside within paths matching activestorage/app/**/*.rb. (Also, arguably, the routes for activestorage should be documented.)

In particular, the activestorage models and included files at activestorage/app/models/active_storage/*.rb are crucial understanding for anyone coding custom analyzers, previewers, etc.

As documentation already exists within these files, this was likely an oversight. I'd like to request whitelisting these directories for documentation purposes.

@rails-bot this is still happening with master. (Just checkout and run yard server.)
I'm going to submit a commit though. It's a one-line fix.

Er. Closed accidentally.
