The dependabot refused to update some dependencies anyway. Maybe it
conservatively checks if all intra dependencies meet a certain version?

backout of commit 58744d9573
I noticed some cargo dependencies aren't caught by the dependabot. For example,
there are gix updates, but the dependabot somehow thinks it's not possible to
update.
```

```
I don't know what's wrong, but let's try without the grouped updates as it was
working before.
FWIW, this issue looks similar:
