Infer section labels

Dry-run: https://gitlab.com/gitlab-org/quality/triage-ops/-/jobs/668401727

SUPER LONG. Mostly just adding labels. Searching for "based on" can give me:

Setting label(s) ~"devops::create" ~"group::ecosystem" ~"section::dev" based on ~"Category:FE/UX Foundations" ~"group::ecosystem".
/label ~"devops::create" ~"group::ecosystem" ~"section::dev"
