ℹ️ I removed this because (1) this list is not generated by package-table anymore since 9459790 (package-table also does not have support for the Go Reference column), and (2) there's no package-list.json in this repository to generate it.

LGTM

RE failing GH actions: We can ignore. Link check is flagging GH short link notation (i.e. link text like jeremy-ellis-tech/net-ipfs-http-client, ok) and spelling check is flagging part of a URL (codecov, ok).
