I18N: Use wp.i18n for translatable strings in wp-admin/js/post.js.

This removes the usage of `wp_localize_script()` for passing translations to the script and instead adds the translatable strings in the script directly through the use of `wp.i18n` and its utilities.

Props swissspidy, ocean90.
See #20491.
Fixes #50599.
