Function invocations now billed per unit

Vercel updated its billing model to charge for serverless function invocations on a per-unit basis rather than previous pricing structures. This change affects how customers are charged for executing functions on the Vercel platform, potentially altering cost calculations for applications with varying invocation volumes. The new billing approach provides more granular and usage-based pricing for function executions.
