Remove bundled translation file in favour of wp.org distributed file.

[peterwilsoncc]

Description of the Change

Removes the bundled translation file, localization/simple-page-ordering.pot, in favour of using the version distributed by WordPress.org.

Since WordPress 4.6, plugins hosted on the WordPress Plugin Repository no longer need to include pot files as Core will automatically download the files from the translation repository, see this make/core post.

As a result of this, plugins can remove bundled .pot files.

Closes #255

How to test the Change

1. Checkout this branch
2. Run npm ci; npm run build
3. Delete the localization directory in the plugin folder, if required
4. Go to Settings > Genneral
5. Set the language to Français
6. Go to the updates page, /wp-admin/update-core.php
7. If the Traductions section contains a button, click it to update your translations from WP.org
8. Navigate to the pages screen, /wp-admin/edit.php?post_type=page
9. In the top navigation ensure that Sort by Order is displayed as Trier par ordre
10. Return to the General settings page and return the site to your default language to avoid confusion later.
