CI: Shorten HTML header

Information about sourceBranch and sourceCommit is already encoded in
the testBranch name, making it redundant in the HTML header.
Also remove the Job Trigger and Target Branch lines, as these parameters
provide limited value and are not particularly relevant for the report.
