Remove default media: 'screen' for stylesheet tag in line with Rails defaults

[brendon]

Rails now doesn't include the media attribute by default for stylesheet_link_tag but the default for vite_javascript_tag has media: 'screen':

https://github.com/ElMassimo/vite_ruby/blob/98d3d5f452d82cfc25720ed85be83f4b43b45d93/vite_rails/lib/vite_rails/tag_helpers.rb#L44

https://github.com/rails/rails/issues/41213

It'd be a breaking change but would keep things in line with the new rails defaults.

vite_stylesheet_tag would now also not return a media attribute since it relies on stylesheet_link_tag without any default options.
