CI(promote-compatibility-data): fix job (#8871)

## Problem

`promote-compatibility-data` job got broken and slightly outdated after 
- #8552 -- we don't upload
artifacts for ARM64
- #8561 -- we don't prepare
`debug` artifacts in the release branch anymore

## Summary of changes
- Promote artifacts from release PRs to the latest version (but do it
from `release` branch)
- Upload artifacts for both X64 and ARM64
