Jonathan Hefner dd884eb425 Pass default values for translate through I18n
A default value can be a string that needs interpolation, Hash that
needs resolution via the `:count` option, or a Proc that needs
evaluation.  Therefore, pass default values through `I18n.translate` to
handle these cases.

Fixes #26032.
Fixes #41277.
Fixes #41380.

* The `translate` helper now passes `default` values that aren't
translation keys through `I18n.translate` for interpolation.
*Jonathan Hefner*
* Adds option `extname` to `stylesheet_link_tag` to skip default
`.css` extension appended to the stylesheet path.
Before:
```ruby
stylesheet_link_tag "style.less"
# <link href="/stylesheets/style.less.scss" rel="stylesheet">
```
After:
```ruby
stylesheet_link_tag "style.less", extname: false, skip_pipeline: true, rel: "stylesheet/less"
# <link href="/stylesheets/style.less" rel="stylesheet/less">
```
*Abhay Nikam*
* Deprecate `render` locals to be assigned to instance variables.
*Petrik de Heus*
* Remove legacy default `media=screen` from `stylesheet_link_tag`.
*André Luis Leal Cardoso Junior*
* Change `ActionView::Helpers::FormBuilder#button` to transform `formmethod`
attributes into `_method="$VERB"` Form Data to enable varied same-form actions:
<%= form_with model: post, method: :put do %>
<%= form.button "Update" %>
<%= form.button "Delete", formmethod: :delete %>
<% end %>
<%# => <form action="posts/1">
=> <input type="hidden" name="_method" value="put">
=> <button type="submit">Update</button>
=> <button type="submit" formmethod="post" name="_method" value="delete">Delete</button>
=> </form>
%>
*Sean Doyle*
* Change `ActionView::Helpers::UrlHelper#button_to` to *always* render a
`<button>` element, regardless of whether or not the content is passed as
the first argument or as a block.
<%= button_to "Delete", post_path(@post), method: :delete %>
<%# => <form action="/posts/1"><input type="hidden" name="_method" value="delete"><button type="submit">Delete</button></form>
<%= button_to post_path(@post), method: :delete do %>
Delete
<% end %>
<%# => <form action="/posts/1"><input type="hidden" name="_method" value="delete"><button type="submit">Delete</button></form>
*Sean Doyle*, *Dusan Orlovic*
* Add `config.action_view.preload_links_header` to allow disabling of
the `Link` header being added by default when using `stylesheet_link_tag`
and `javascript_include_tag`.
*Andrew White*
* The `translate` helper now resolves `default` values when a `nil` key is
specified, instead of always returning `nil`.
*Jonathan Hefner*
* Add `config.action_view.image_loading` to configure the default value of
the `image_tag` `:loading` option.
By setting `config.action_view.image_loading = "lazy"`, an application can opt in to
lazy loading images sitewide, without changing view code.
*Jonathan Hefner*
* `ActionView::Helpers::FormBuilder#id` returns the value
of the `<form>` element's `id` attribute. With a `method` argument, returns
the `id` attribute for a form field with that name.
<%= form_for @post do |f| %>
<%# ... %>
<% content_for :sticky_footer do %>
<%= form.button(form: f.id) %>
<% end %>
<% end %>
*Sean Doyle*
* `ActionView::Helpers::FormBuilder#field_id` returns the value generated by
the FormBuilder for the given attribute name.
<%= form_for @post do |f| %>
<%= f.label :title %>
<%= f.text_field :title, aria: { describedby: f.field_id(:title, :error) } %>
<%= tag.span("is blank", id: f.field_id(:title, :error) %>
<% end %>
*Sean Doyle*
* Add `tag.attributes` to transform a Hash into HTML Attributes, ready to be
interpolated into ERB.
<input <%= tag.attributes(type: :text, aria: { label: "Search" }) %> >
# => <input type="text" aria-label="Search">
