Rails 7.1 support

[cpgo]

Just bumped the activerecord version and fixed a minor change related to the default_timezone setter.

Taking a closer look at rails 7.1 release notes but as far as I could find there are no more changes needed.

@cpgo Please rebase to allow tests to run (updated in the master)

[cpgo]

@EugZol done

[cpgo]

Not exactly sure how to handle this, would something like this work?

if Rails.gem_version < Gem::Version.new("7.1")
  ActiveRecord.default_timezone = :utc
else
  ActiveRecord::Base.default_timezone = :utc
end

[EugZol]

@cpgo sure!

[cpgo]

Changed the version check to look at activerecord version instead of rails. Tests are passing locally, not sure why the CI is breaking, will take a better look later

[EugZol]

Seems it should be the other way around :)

[cpgo]

Yep :upside_down_face: But I see some weird UTF encoding errors on my CI run now
