ci(docs): trigger docs deploy when the deploy scripts change

The Documentation workflow runs dev-tools/docs/mike_deploy.sh and
smoke_check_pages.sh, but its push/PR path filters did not include
dev-tools/docs/**. A fix that touched only those scripts therefore merged
without ever re-running the docs deploy, leaving the live site stale.

Add dev-tools/docs/** to both path filters (and .github/workflows/docs.yml
to the PR filter for parity) so script changes trigger a deploy.
