staging: Deploy gitweb lister

That's also an excuse to have another round of checks on the pipeline concurrency issue (should be fixed). And the auto-deploy of the swh-next-version branch of swh-charts.

Plan:

• Tag swh.lister v5.8.0
• debian package: Loop, fix, package 'til it works [1]
• scheduler0.staging: Upgrade python3-swh.lister (depends on ^)
• scheduler0.staging: Register new task type (depends on ^)
• swh/infra/ci-cd/swh-charts!93 (diffs) swh-charts: Update docker image
• swh/infra/ci-cd/swh-charts!92 (diffs): swh-charts: Reference new lister
• argocd: Deploy
• Schedule one new instance for listing (depends on the new task type being registered)
• Checks
