Build failing with the same setup issue as D566 (loader-core), due to setup issue in swh-jenkins-jobs.

Digging the logs:

stderr: fatal: repository 'https://forge.softwareheritage.org/source/loader-dir.git/' not found

Should be swh-loader-dir.git.
Fix: change the display-name from loader-dir to swh-loader-dir in swh-jenkins-jobs/swh/loader-dir.yml
(it's there now \m/ [1])
