Ask the resolvers which maidr.js version latest is
Source: R/cdn_version.R
maidr_fetch_latest_cdn_version.RdTries jsDelivr's data API, then the npm registry, within one shared time
budget: each request gets whatever the budget has left, and curl enforces
it as a limit on the whole transfer, name resolution included. Never
raises and never warns – a failed lookup must not fail a render – so
every failure, whether the network, an HTTP status, or an answer that is
not JSON or not a version, is NULL.
