Subject: [PATCH] ref(vercel-edge): Remove `@opentelemetry/resources`
 dependency

The bundled `BasicTracerProvider` from `@opentelemetry/sdk-trace-base` statically
imports `defaultResource` from `@opentelemetry/resources` as a fallback
(`mergedConfig.resource ?? defaultResource()`).But we always supply our own
ownresource via `getSentryResource()`, so the fallback never runs. The import
only needs to resolve.

So we shim `@opentelemetry/resources` to a tiny inlined stub during bundling so
the real package is never bundled, then remove it from `dependencies`.

This also avoids pulling OTel's node-only resource detectors into the edge
runtime.
