Re-enable Acala test suites

`request_timeout_seconds: 90` on Subway's upstream client (added to
`subway-template.yml` in the previous commit) gives Subway enough
time per upstream attempt for Acala storage queries to land before
the 30s default forced it to cycle endpoints. The exclusion added in
PR #621 is no longer needed and is removed; the exclusion comment is
narrowed to bifrostKusama, which still lacks a workable endpoint set.
