revert: undo accidental direct-to-main docs pushes

Reverts two commits that were pushed directly to main by mistake:
- b9e1f6d (Google Search Console meta tag)
- 836cfa8 (Data Privacy Stack footer link)

The footer link is now redundant: #2102 added its own `copyright` entry
pointing to dataprivacystack.org, leaving main with a duplicate top-level
`copyright:` key. This revert removes our duplicate and the orphaned meta
tag so main matches the post-#2102 (Zensical) state. The Search Console
meta tag is re-introduced properly in a follow-up PR.
