"Upcoming Release Changes" PR workflows not running

[YaroShkvorets]

i.e #1864

As a result final checks before the release are not performed, including publishing CLI RC release.

The issue here is that GitHub doesn't trigger workflows from events created by other workflows to avoid infinite loop: peter-evans/create-pull-request#48

Possible workarounds:

• create this PR with different PAT token
• Github app
• cron ?
• manual dispatch ?
