[#1780] Add Welsh translation for DB form

[mdeuk]

Relevant issue(s)

Fixes #1780
Fixes https://github.com/mysociety/whatdotheyknow-private/issues/262
#1775

What does this do?

1. Reconciles changes for /lib/views/help/contact.html.erb from Signpost data breach form #1775 into Welsh translation.
2. Adds partial translation for /lib/views/help/report_a_data_breach.html.erb

Why was this needed?

Data breach form was not translated to Welsh.

Implementation notes

The breach form, itself, is only a partial translation, as:

• the heading, at level 1, is not translated (now rectified)
• the further information text, and everything following, is not translated
• related file report_a_data_breach_thank_you.html.erb is not translated

Notes to reviewer

I had a bit of trouble with Git commits - hopefully all makes sense.

We will need to follow-up on the remaining parts, but this can be done later on.

• Rendering the 'help/contact_form' partial within _contact_form.cy.html.erb may lead to unintended recursion if it resolves to the current localized partial. Consider explicitly referencing the non-localized version or ensuring the view lookup selects the intended file.

<%= render :partial => "help/contact_form", :locals => { :form_id => 'writing-help' } %>

lib/views/help/_contact_form.cy.html.erb:166

• Similar to the earlier render call, this may also trigger recursive rendering if the lookup finds the current localized partial. Verify that the intended (possibly unlocalized) partial is referenced to avoid recursion.

<%= render :partial => "help/contact_form", :locals => { :form_id => 'wdtk' } %>
