Fix sidekiq SLI on stage group error budget dashboard

• Fix sidekiq SLI panels on error budget stage group dashboard not showing any series. This broke because aggregationSets.shardComponentSLIs is hardcoded in sliOverviewMatrixRow function (https://gitlab.com/gitlab-com/runbooks/-/blob/e0352a3be6005d1ae0ceac205d5a361e33c132eb/libsonnet/gitlab-dashboards/metrics_catalog_dashboards.libsonnet#L89). This function is also called from stage group dashboards which needs to use aggregationSets.serviceComponentStageGroupSLIs instead. source
• Fix expectMultipleSeries flag not passed in service dashboard. This effectively sets line width to 1 instead of 2 (thinner line because we have multiple series from each shard in the dashboard)
• Added featureCategory: 'not_owned' for sidekiq_queueing so it doesn't show up in error budget's SLI panels and not counted in error budget attribution. Also removes sidekiq_queueing from ignored_components
