The `type: :feature` is automatically detected by RSpec because these
tests are inside the `spec/features` folder. Using `feature` re-adds a
`type: :feature` to these files, which will result in a conflict when we
upgrade to Rails 5.1's system tests.
Because of this change, we also need to change `background` to `before`
or else these tests will fail.
The content 'An example legislation process' is already present before
we click the "All" link.
Not checking the page content properly sometimes resulted in the second
click being executed before the first request had been completed, making
the spec fail.
By checking the "All" link isn't present anymore, we guarantee the
request has been completed before trying to click the 'An example
legislation process' link.
Updating it required reorganizing the form so translatable fields are
together.
We also needed to add a `hint` option to the form label and input
methods so the hint wouldn't show up for every language.
Finally, the markdown editor needed to use the same globalize attributes
as inputs, labels and hints, which adds a bit of duplication.
