Add `evaluation details` to `finally` hook stage

[beeme1mr]

Add evaluation details to finally hook stage.

Notes

This breaks the signature of the finally stages based on this spec enhancement. It is not considered a breaking change to the SDK because hooks are marked as experimental in the spec, and the change has no impact on known hooks.

- finally(hookContext, hookHints)
+finally(hookContext, evaluationDetails, hookHints)

Acceptance criteria:

• finally hook stage modified
• associated tests

Follow ups:

• update contribs
