Docs: make aspire otel the primary telemetry command and rename traces reference to trace

[Copilot]

The CLI docs were still inconsistent with the command rename from aspire telemetry to aspire otel, and the trace subcommand naming needed to reflect the current aspire otel trace shape. This updates command reference pages, nav, and links so docs present the new primary names while preserving alias/back-compat guidance.

• CLI command reference alignment

  • Renamed the trace command reference page route from aspire-otel-traces to aspire-otel-trace.
  • Updated command tables/see-also links and command text to use aspire otel trace.
  • Clarified wording to reference the Dashboard OpenTelemetry API on otel command pages.

• Backward-compatibility handling

  • Added a dedicated aspire telemetry alias page that points readers to aspire otel.
  • Added an explicit alias note on the primary aspire otel page (aspire telemetry remains supported as a backward-compatible alias).

• Navigation and cross-doc link updates

  • Updated sidebar CLI entries to aspire otel trace and the new slug.
  • Updated prose/examples across related docs (search/filter, dashboard, telemetry, what’s new) to point to aspire otel trace.
  • Added redirect from /reference/cli/commands/aspire-otel-traces/ to /reference/cli/commands/aspire-otel-trace/.

:::note
`aspire telemetry` is a backward-compatible alias for `aspire otel`.
