Duplicate stylesheet_link_tag inserted in new rails 8.0 app

[feral-grimalkin]

New rails 8.0 app generated with rails new test8 -c postcss (or bootstrap, or bulma) contains the following lines in application.html.erb:

<%# Includes all stylesheet files in app/assets/stylesheets %>
<%= stylesheet_link_tag :app, "data-turbo-track": "reload" %>
<%= javascript_importmap_tags %>
<%= stylesheet_link_tag "application", "data-turbo-track": "reload" %>

The first stylesheet_link_tag comes from rails itself, the second one comes from cssbundling-rails, likely introduced by this PR #15, so the application.css file gets included twice.
