With the combination of Propshaft and importmap-rails, the app/javascript directory added by importmap-rails cannot be excluded

[shrkw]

Rails (8.1.1)
propshaft (1.3.1)
importmap-rails (2.2.2)

When Propshaft and importmap-rails are used together, the contents of Rails.application.config.assets look like this. Some entries such as app/javascript are registered as Pathname objects:

blog81b(dev):001> Rails.application.config.assets
=> 
{:paths=>
  ["/workspaces/sandbox-ruby/blog-81b/app/assets/images",
   "/workspaces/sandbox-ruby/blog-81b/app/assets/stylesheets",
   #<Pathname:/workspaces/sandbox-ruby/blog-81b/app/javascript>,
   #<Pathname:/workspaces/sandbox-ruby/blog-81b/vendor/javascript>,
   "/usr/local/lib/ruby/gems/3.3.0/gems/actionview-8.1.1/app/assets/javascripts"],

However, when Propshaft evaluates excluded_paths, they are processed as strings, so any paths registered as Pathname objects cannot be excluded.

app.config.assets.paths = app.config.assets.paths.without(Array(app.config.assets.excluded_paths).collect(&:to_s))

A straightforward fix would look like this, but would it be acceptable to open a PR like this?

app.config.assets.paths = app.config.assets.paths.without(Array(app.config.assets.excluded_paths).collect(&:to_s))
app.config.assets.paths = app.config.assets.paths.without(Array(app.config.assets.excluded_paths))
