Add ActiveSupport::ExecutionContext controller setting for Rails 7+

[Blayr]

This adds missing ActiveSupport::ExecutionContext used by ActiveRecord QueryLogs
https://api.rubyonrails.org/classes/ActiveRecord/QueryLogs.html

Link to the introduction of this behaviour in Rails/ActionPack (Rails 7.0):
https://github.com/rails/rails/blob/984c3ef2775781d47efa9f541ce570daa2434a80/actionpack/lib/action_controller/metal/instrumentation.rb#L51

Before this change, having

# application.rb (rails app)
config.active_record.query_log_tags_enabled = true
config.active_record.query_log_tags = [ :application, :controller, :action, :job ]

would not yield :controller or :action when the log was being generated

Before

SELECT `users`.`id` FROM `users` WHERE `users`.`id` = 1
/*application=someapp*/

After changes in this PR:

SELECT `users`.`id` FROM `users` WHERE `users`.`id` = 1
/*application=someapp,action='index',controller='users'*/
