feat(telemetry): add SubscriptionId and TenantId passthrough for MSDO CLI

[DimaBir]

Summary

• Add optional subscriptionId and tenantId inputs to the GitHub Action
• Forward them as MSDO_SUBSCRIPTIONID / MSDO_TENANTID environment variables to the MSDO CLI process
• Fully backward compatible — no behavior change when inputs are omitted

Context

Supports ADO PBI 36365209 — enabling MSDO CLI telemetry correlation with Defender for Cloud (dCSPM) subscription data.

Task: AB#36805549
Parent PBI: AB#36805486

Changes

File	Change
action.yml	+2 optional inputs: subscriptionId, tenantId
src/msdo.ts	Set env vars before client.run() when inputs are provided
lib/msdo.js	Compiled output

Test plan

• Build passes (npm run build)
• No regression — existing tests have same results as main
• Env vars only set when inputs are provided (null-safe via isNullOrWhiteSpace)
• Works for both run and upload code paths
• E2E: validate CLI picks up env vars once CLI-side changes land
