fix(stash): add /blobs PVC storage

[schnerring]

Description

As per v0.20.0 release notes:

The Filesystem storage system is recommended for large libraries, and is the default for new systems.

Docker users: please ensure that the Binary Data filesystem path is mapped to a persistent location if you choose to use the Filesystem binary storage type. Not doing so may result your binary data (scene covers, performer images etc) being lost.

This PR adds the binary storage PVC at /blobs (the install wizard default).

I also noticed that the questions.yaml doesn't allow customizing the /generated PVC. It was added in 3c90d1f. Was this intended or an oversight @xstar97?
