Exact build version is not emitted for some builds

In CI, the build logs include the stack component versions, but for some builds the version is essentially constant. For example in a flaky test report for the serverless flavour, I see this

```
╭───────────────┬───────────────────────┬───────────────────╮
│ SERVICE │ VERSION │ STATUS │
├───────────────┼───────────────────────┼───────────────────┤
│ kibana │ serverless (security) │ healthy │
│ fleet │ serverless (security) │ healthy │
│ elasticsearch │ serverless (security) │ healthy │
│ elastic-agent │ 8.17.4 │ running (healthy) │
╰───────────────┴───────────────────────┴───────────────────╯
```
This version gives no useful information to allow a developer to be able to correlate the behaviour with the artefact that gives the behaviour. The version should include either a tag or a sha for each of the artefacts (preferably both).

Ideally, the information about version would be reported to the github issue/pull request that reports the CI outcome since the details shown here are burried deep in extensive logs that are not persisted indefinitely, resulting is unnecessary work and potentially lost useful information.
