Restore docs workflow installs after adding the WebFetch dependency

The main branch push introduced a new root dependency for WebFetch fixes, but
package-lock.json was not refreshed, so the docs workflow's npm ci step failed
before it could even build VitePress. This syncs the lockfile, upgrades the
docs workflow to Node 22 for the current parser dependency requirements, and
includes package-lock.json in the workflow trigger set.

Constraint: The docs pipeline uses npm ci, which requires package.json and package-lock.json to stay exactly in sync
Rejected: Leave the workflow on Node 20 | continues to emit avoidable engine warnings for current docs parser dependencies
Rejected: Switch docs workflow from npm ci to npm install | weakens reproducibility instead of fixing the lockfile contract
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Whenever root dependencies change, keep package-lock.json in the same commit so docs and other npm-based workflows remain green
Tested: npm ci
Not-tested: Remote GitHub Actions rerun after pushing this fix
