🩹 [Patch]: Remove output access hints from logs (#55)

Removes the output access hint text from the action logs to avoid
confusion when the action is used directly or nested in another
composite action. The output grouping and output content display remain
unchanged.

- Fixes #54

## Changes

- Remove access-hint printing in `scripts/outputs.ps1`
- Simplify composite output test by removing access-pattern demo and
help-text validation

## Rationale

The access pattern differs for direct vs nested usage, so printed hints
can be misleading. Removing the hint avoids confusion while still
showing the output values.
