🗒️ I updated the lock file to be able to test against Rails 7.1.0. Let me know if I should split this into a separate commit or PR.

🤔 I had to add the defined? check to work around certain test failures. I assume that Rails will be defined when this file is loaded in a real app. Is there a better way to do this?

That approach would have worked, but changed my mind as I'd like to provide more information in case users see it in the docs and try to use it in an older version of Rails.
Rails 7.1 introduced a `picture_tag` helper.[^1] This commit adds a corresponding `vite_picture_tag` helper that handles resolving assets via Vite, but otherwise behaves the same as `picture_tag`. It is only exposed for Rails >= 7.1.0. [^1]: rails/rails#48100

I realize this PR is ~9 months old, but this line has different output for me.
Running Rails 7.1.3.4, the type attribute is different. I see a failure like:
Failure:

Maybe related to rails/rails#48266 ?
Curious to see a CI run after #467

@mjankowski I can't reproduce what you are seeing locally. Using vite_ruby @ main, and running bundle up to get the latest gems, the test still passes for me:
$ bundle exec rake test TEST=test/helper_test.rb
...
14 tests, 36 assertions, 0 failures, 0 errors, 0 skips
$ bundle show rails
/Users/mbrictson/.rbenv/versions/3.1.1/lib/ruby/gems/3.1.0/gems/rails-7.1.3.4
Digging through the Rails source, my guess is that ActionView::Template::SimpleType is somehow being used in your environment, causing the mime type lookup to return svg instead of the correct image/svg+xml.
I found this comment:
SimpleType is mostly just a stub implementation for when Action View is used without Action Dispatch.
So maybe Action Dispatch isn't being loading in your environment, for some reason?

Ah, thanks ... think I tracked it down.
I have a branch going trying to get rid of some of deprecation noise during spec run, and I did a bit of branch jam-up on myself, and I think I had eager_load disabled during that failure, which may explain the lack of the template being present (and it falling back to just ext string) during the run.
