Auto merge of #12342 - epage:ci, r=<try>

chore(ci): Automatically test new packages by using `--workspace`

### What does this PR try to resolve?

This is a part of #11987 that was unblocked by #12321 and #11993

### How should we test and review this PR?

Relying on CI to verify this

I'd prefer to move the `cargo test --workspace` step earlier but we run out of disk space if we do (we currently only have 661 MB of headroom of windows-gnu)

See the individual commits for smaller chunks and explanations for why changes were made.
