André Luis Leal Cardoso Junior 1280620767 Remove legacy media=screen default from stylesheet_link_tag.
If the media attribute is omitted, the default for web browsers is "all", meaning that by default links apply to all media.

Before:

```ruby
> stylesheet_link_tag "style"
=> <link href="/assets/style.css" media="screen" rel="stylesheet" />
```

After:

```ruby
> stylesheet_link_tag "style"
=> <link href="/assets/style.css" rel="stylesheet" />

```

The current behavior is not going to change for existing applications.

For newly built applications, the media attribute is not going to be added by default. Which can be configured using the following:

```
Rails.application.config.action_view.stylesheet_media_default = false
```
