Fix staging deploy by upgrading Shakapacker to 8.2.0

React on Rails 16.0.1.rc.2 requires Shakapacker >= 8.2.0 for proper
packer_type detection. Without this, the clean task invocation fails
with 'Don't know how to build task :clean' during assets:precompile.

This upgrade ensures the correct 'shakapacker:clean' task is invoked
instead of the non-existent ':clean' task.
