ci(mergify): disable inherited T-ID title/commit-message checks in this repo

The central baseline at vyos/mergify:.mergify.yml enforces a
`T<digits>: <text>` (optional `scope: ` prefix) format on PR titles
and every commit's first line — a convention from vyos/vyos-1x and
sibling code repos where engineering work tracks against a Phorge
task.

vyos-documentation has never enforced this. Recent merged PRs use
conventional-commits style (`fix(ext): …`, `ci(...): …`,
`chore(deps): …`) without an upstream T-ID. After the
`extends: mergify` adoption in #2005, the inherited rules
started labeling every such PR `invalid-title` and
`invalid-commit-title` — pure noise for this repo.

Override the two rules by name (Mergify `extends:` semantics:
same-name rules in the child REPLACE the parent's). Conditions are
constructed to never match (`closed and -closed`), so the `toggle`
action always falls into the "remove label" branch and also clears
the labels from any PR that picked them up since #2005 merged.
