What this PR does / why we need it:
This update clarifies the requirement for units within the original label value when making a Duration comparison. It ensures that users understand the necessity of including a unit suffix (e.g., 'ms', 'h') for accurate parsing and comparison.
[ ] Title matches the required conventional commits format, see here
Note that Promtail is considered to be feature complete, and future development for logs collection will be in Grafana Alloy. As such, feat PRs are unlikely to be accepted unless a case can be made for the feature actually being a bug fix to existing behavior.
[ ] Changes that require user attention or interaction to upgrade are documented in docs/sources/setup/upgrade/_index.md
[ ] For Helm chart changes bump the Helm chart version in production/helm/loki/Chart.yaml and update production/helm/loki/CHANGELOG.md and production/helm/loki/README.md. Example PR
[ ] If the change is deprecating or removing a configuration option, update the deprecated-config.yaml and deleted-config.yaml files respectively in the tools/deprecated-config-checker directory. Example PR
