ci: fix release job concurrency issue

[wrn14897]

• Multiple workflow runs can now run in parallel for different commits
• The release job (Docker builds) won't be cancelled once it starts
• New commits will queue their release jobs to run after the current one finishes (due to the concurrency group per matrix item)
