package caller: pass AWS secrets via secrets: inherit

GitHub Actions doesn't expose the 'secrets' context in 'with:' when
calling a reusable workflow. The companion PR on the shared workflow
(ModernRelay/.github) moves the four AWS values into
on.workflow_call.secrets; this caller drops them from 'with:' and adds
'secrets: inherit' so all four flow through masked.

Trailing from PRs #33 and #34.
