CI(promote-compatibility-data): fix job

[bayandin]

Problem

promote-compatibility-data job got broken and slightly outdated after

• CI(build-and-test): run regression tests on arm #8552 -- we don't upload artifacts for ARM64
• CI(regress-tests): run less regression tests #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

Checklist before requesting a review

• I have performed a self-review of my code.
• If it is a core feature, I have added thorough tests.
• Do we need to implement analytics? if so did you add the relevant metrics to the dashboard?
• If this PR requires public announcement, mark it with /release-notes label and add several sentences in this section.

Checklist before merging

• Do not forget to reformat commit message to not include the above checklist
