Improve job name for clarity in workflow runs

Previously, the job name in the workflow matrix only displayed version
numbers, resulting in ambiguous labels like

```
Ruby / test (3.1, 4.4, 3.0)
```

This commit updates the job name to explicitly include the technology
names alongside their versions:

```
CI / Test (Ruby 3.1, MongoDB 4.4, SQLite 3.0)
```

This change makes it immediately clear which version number corresponds
to which technology, improving readability and reducing confusion when
reviewing workflow results.
