When translating a `<button>` element's contents, it is tedious to make
the translation text available to a block scope.
For instance, when rendering a `<button type="submit">` with an SVG
element as its child, passing translated label text to that SVG
element's [`<title>`][svg-title] element requires an extra call to
`I18n.translate`.
Prior to this commit, doing so would require a double lookup of the
translation key:
```erb
<%# one time here, implicitly %>
<%= form.button do %>
<svg>
<title>
<!-- one time here, explicitly -->
<%= translate("helpers.submit.post.create") %>
</title>
<!-- ... -->
</svg>
<% end %>
```
This commit modifies the `ActionView::Helpers::FormBuilder#button` to
check for invocations that are passed a block, and conditionally yield
the contents of `submit_default_value` as the argument.
The new view code might look something like this:
```erb
<%= form.button do |text| %>
<svg>
<title><%= text %></title>
<!-- ... -->
</svg>
<% end %>
```
Callers of the helper are still free to omit the block parameter.

= Action View
Action View is a framework for handling view template lookup and rendering, and provides
view helpers that assist when building HTML forms, Atom feeds and more.
Template formats that Action View handles are ERB (embedded Ruby, typically
used to inline short Ruby snippets inside HTML), and XML Builder.
You can read more about Action View in the {Action View Overview}[https://edgeguides.rubyonrails.org/action_view_overview.html] guide.
