devel/ruby-activestorage70: update to 7.0.4

* Fixes proxy downloads of files over 5MiB

  Previously, trying to view and/or download files larger than 5mb stored in
  services like S3 via proxy mode could return corrupted files at around
  5.2mb or cause random halts in the download.  Now,
  ActiveStorage::Blobs::ProxyController correctly handles streaming these
  larger files from the service to the client without any issues.

  Fixes
