chore: remove error messages from bug report template (#27037)

## **Description**

Since the field '### Error messages or log output' is not present in
Jira, we no longer want to make it a mandatory requirement to recognize
the bug report template in GitHub.

Thanks to this change, the issues created by **issuebridge** app (which
replicates on GitHub the tickets we create in Jira), should be
recognized as bug reports by our GitHub Actions.

> [!NOTE]
> **Low Risk**
> Low risk: only changes the GitHub template-title matcher for bug
reports by removing one required heading, which may slightly broaden
what issues are auto-labeled as bug reports.
> 
> **Overview**
> Bug report issue template detection is relaxed by dropping the `###
Error messages or log output` section from
`bugReportIssueTemplateTitles` in `.github/scripts/shared/template.ts`.
> 
> This allows issues missing that heading (e.g., synced from Jira) to
still match the bug report template and be processed by the existing
labeling workflow.
