fix(padrino): avoid ActiveSupport's try

[osbre]

Description 📖

This pull request fixes a NoMethodError in vite_padrino when an entrypoint imports a shared chunk.

Background 📜

This was happening because vite_preload_tag calls try(:request), and try comes from ActiveSupport, which Padrino doesn't load. Vite emits a modulepreload tag whenever two entrypoints import the same module, so any such app crashes when rendering vite_javascript_tag:

NoMethodError - undefined method 'try' for an instance of App

The Fix 🔨

By changing the try calls to plain respond_to? checks. Early hints are still sent when the request supports them.

Screenshots 📷

N/A. Tested with a generated Padrino app with two entrypoints sharing a module, after vite build: before, a 500 error; after, a 200 with the <link rel="modulepreload"> tag rendered.
