chore(publish): [v7] Use craft config from merge target branch for release preparation (#10763)

Update our prepare release workflows on the `v7` branch to use
the craft config from the merge target branch (which for v7 releases
should always be `v7`) instead of the config from the default branch
(`develop` in our case).
