chore: remove unused stale reusable workflow (#160)

The stale reusable workflow is not used by any iExec repository.
Remove the workflow, its package directory, its release-please
config and manifest entries, and its README section.

Existing stale-v1.0.0 and stale-v1.0.1 tags and releases are kept.
