mgr/dashboard: Add linter for unclosed HTML tags

[p-se]

Adds html-hint to the npm run lint command and hence, it's automatically added to run-frontend-unit-test.sh, which is called on pull request creation. Ensures closed HTML tags. It found the issue spotted by @s0nea.

user@home ~/src/ceph-4/src/pybind/mgr/dashboard/frontend (wip-pna-fix-tag*) $ npx htmlhint -r tag-pair src/app
