More descriptive Github checks log message

### What feature do you want to see added?

Currently, the status line that informs that the check is published looks like this:
```
[GitHub Checks] GitHub check (name: Jenkins, status: completed) has been published.
```
If the status is completed, it is also worth adding information about the conclusion (one of the values: `action_required`, `cancelled`, `failure`, `neutral`, `success`, `skipped`, `stale`, `timed_out`)
so log message will be as below:
```
[GitHub Checks] GitHub check (name: Jenkins, status: completed, conclusion: failure) has been published.
```

The code responsible for this:
https://github.com/jenkinsci/github-checks-plugin/blob/e9ce039f678d13bf665736571b6cca8432c838ba/src/main/java/io/jenkins/plugins/checks/github/GitHubChecksPublisher.java#L99
I have the impression that we just need to change the code as below, but I haven't checked that:
```diff
- buildLogger.log("GitHub check (name: %s, status: %s) has been published.", gitHubDetails.getName(),
- gitHubDetails.getStatus());
+ String conclusion = gitHubDetails.getConclusion();
+ if(conclusion != null) {
+ buildLogger.log("GitHub check (name: %s, status: %s, conclusion: %s) has been published.", gitHubDetails.getName(),
+ gitHubDetails.getStatus(), conclusion);
+ }else {
+ buildLogger.log("GitHub check (name: %s, status: %s) has been published.", +gitHubDetails.getName(),
+ gitHubDetails.getStatus());
+ }
+
```

Unfortunately no, because it is too complicated from the point of view of corporate procedures.
