maint/downgrade-dependencies: Update exceptions.
Fixes the minimal-versions
failure:
error: package ID specification `futures-lite@1.0.0` did not match any packages
Did you mean one of these?
futures-lite@2.0.0
(we don't actually need to un-downgrade futures-lite
anymore)
But we do need to un-downgrade event-listener
(async-global-executor
needs event_listener::EventListener
to be UnwindSafe
,
and in event-listener 3.0.0
, they are not)
