Core Rule Set: WordPress's names and addresses pass on more fields (closes #245)

Each field skips only the rules its recorded requests set off:

- page on all of wp-admin, and the JSON fields title, excerpt and name
  on /wp/v2/ routes: 930120, 932120, 932250 and 932260;
- p, postId and slug on all of wp-admin, and the JSON slug on /wp/v2/
  routes: 932120 and 932260, since WordPress writes these as slugs;
- url on the block editor's link previews and embeds, and a commenter's
  url: 930120 and 932120.

Every field keeps 932235. Add 61 requests recorded from WordPress 7.1.4
with these fields.
