Description

Is your feature request related to a problem? Please describe.

Today there's no way in a workflow to know how many attempts an activity made before failing.
This has come up in community slack where a user wanted to report this number from a workflow.

Describe the solution you'd like

Expose an attempts field in ActivityFailure, the SDK has this information in the ActivityTaskStarted event.

The field should be populated in case the activity ended up as failed or canceled.

Research direction

Start with ActivityFailure and the ActivityTaskStarted definition in temporal/api/history/v1/message.proto, which contains the attempts information. Trace how that value is exposed across the listed Go, Java, Core, TypeScript, Python, .NET, and PHP SDK tickets; done means failed or canceled activities report their attempt count.
