Upgrade to rails 7.1

[jcoyne]

This needs to run bin/rails active_storage:update before being complete, but it's running into trouble:

bin/rails active_storage:update
DEPRECATION WARNING: DeprecatedConstantProxy without a deprecator is deprecated (called from <main> at /Users/jcoyne85/workspace/sul-dlss/dlme/config/application.rb:7)
DEPRECATION WARNING: Support for `config.active_support.cache_format_version = 6.1` has been deprecated and will be removed in Rails 7.2.

Check the Rails upgrade guide at https://guides.rubyonrails.org/upgrading_ruby_on_rails.html#new-activesupport-cache-serialization-format
for more information on how to upgrade.

      PaperTrail 12.3.0 is not compatible with ActiveRecord 7.1.2. We allow PT
      contributors to install incompatible versions of ActiveRecord, and this
      warning can be silenced with an environment variable, but this is a bad
      idea for normal use. Please install a compatible version of ActiveRecord
      instead (>= 5.2, < 7.1). Please see the discussion in paper_trail/compatibility.rb
      for details.

@corylown we probably don't want the db/ files in here.

We definitely don't. They're removed.

I think we're now on a version of papertrail that's compatible with Rails 7.1: https://github.com/paper-trail-gem/paper_trail/blob/v15.1.0/README.md#1a-compatibility

Updating to spotlight >= 3.6.0.beta8 should fix the test failure because projectblacklight/spotlight@b51a8ac is included.
