AWS AWSEC2: Add T8i instance type to burstable credits documentation
Summary
Adds T8i instance family rows and references to CPU credit tables, launch credit notes, and credit persistence sections; reorders T2/T3/T3a tables.
Security assessment
The change only documents a new burstable instance family (T8i) and its CPU credit behavior. It contains no authentication, encryption, credential, or vulnerability-related content.
Evidence
+T8i | Earned credits, Accrued credits, Spent credits, Surplus credits (Unlimited mode only) | Standard, Unlimited (default) | 7 days (credits persist for 7 days after an instance stops)
