Add rake task to correct title fields within application document

[Lubosky]

📝 A short description of the changes

Added rake task to correct titles for 'press book contact' and 'head of organisation' for 24/25 award year applications to use a whitelisted value where the match can be identified (uppercase/lowercase title, titles having trailing spaces or having a comma)

To run the task use bundle exec rake form_answers:backfill_whitelisted_titles

To get the incorrect titles run the following from Rails console:

require "csv"

query = %{
  SELECT
    form_answers.id,
    form_answers.urn,
    form_answers.document ->> 'head_of_business_title' AS head_of_business_title,
    form_answers.document ->> 'press_contact_details_title' AS press_contact_details_title
  FROM
    form_answers
  WHERE
    form_answers.award_year_id = 19
    AND(form_answers.document ->> 'head_of_business_title' IS NOT NULL
      OR form_answers.document ->> 'press_contact_details_title' IS NOT NULL)
    AND(form_answers.document ->> 'head_of_business_title' NOT IN('Mr', 'Mrs', 'Miss', 'Ms', 'Mx', 'Dr', 'Professor', 'Reverend', 'Sir', 'Baron', 'Baroness', 'Dame', 'Lady', 'Lord')
      OR form_answers.document ->> 'press_contact_details_title' NOT IN('Mr', 'Mrs', 'Miss', 'Ms', 'Mx', 'Dr', 'Professor', 'Reverend', 'Sir', 'Baron', 'Baroness', 'Dame', 'Lady', 'Lord'))
}.squish

result = ActiveRecord::Base.connection.execute(query)

headers = %w(id urn head_of_business_title press_contact_details_title)
file = Rails.root.join("tmp", "output.csv")

CSV.open(file, "w", write_headers: true, headers: headers) do |csv|
  result.to_a.each do |row| 
    csv << [row["id"], row["urn"], row["head_of_business_title"], row["press_contact_details_title"]] 
  end
end
