ci(codeowners): restore ragnorc to engineering and docs roles

Re-adds ragnorc to both roles in the source of truth and regenerates
CODEOWNERS + the ownership tables. This also resolves the standing
inconsistency from #169: branch-protection.json's
bypass_pull_request_allowances still listed ragnorc after his codeowners
removal — the two lists are in sync again (no protection change needed).
