fix: generateOgImageForSite error

[iamStephenFang]

Description

generateOgImageForSite() / generateOgImageForPost() return a Buffer, but in TypeScript’s type definitions, new Response() does not accept Node.js Buffer—it only accepts Web platform BodyInit types (such as Blob, ArrayBuffer, Uint8Array, etc.).

Astro uses Web API type definitions (dom lib) during build time, so Node.js Buffer types won’t match. Just simply convert the Buffer to a Uint8Array or ArrayBuffer to pass type checking.
