docs: add upgrade guide note for publish_allocation_metrics (#26187)

In #25870 we fixed a longstanding bug where allocation metrics were being
collected and published even if `telemetry.publish_allocation_metrics` was
disabled (the default). This change is unexpected enough that we should surface
it in the upgrade guide.

configuration field was unset or set to `false`. If you are monitoring
allocation metrics, you will need to ensure your Nomad clients set this field to
`true`.
