Document describes the process for updating TypeSpec validation rules

Description
This document should describe the essential workflow for updating TypeSpec validation rules and how to handle rule changes with different levels of impact.
1. Rule Impact

Small impact: affects a few configs/specs.
Major impact: affects many or most configs/specs.

2. Workflow — Small Impact

Add/update rule in public/main.
CI runs validation; fix failing specs in the same PR.
After review, create draft PRs for public/main and private/rpsaasmaster.
Fix private repo failures before merging rule to public/main.

3. Workflow — Major Impact

Temporarily disable the rule.
Update all affected configs/specs in a separate PR.
Re‑enable the rule after all updates are complete.
