Docs: Example for additional cache behaviours

[devmarwen]

On SST v2 we had this additionalBehaviors

const site = new NextjsSite(stack, "site", {
  // ... 
  cdk: {
    distribution: {
      // ...
      additionalBehaviors: {
        "/a/*": {
          origin: aOrigin,
        },
        "/b/*": {
          origin: bOrigin,
        },
        "/c/*": {
          origin: cOrigin,
        },
      },
    },
  },
});

How to migrate this to SST v3. Using transform.cdn did not help because it overridden orderedCacheBehaviors/origins SST had generated

const site = new sst.aws.Nextjs("ffd-nextfront-ion", {
  transform: {
    cdn: {
      orderedCacheBehaviors: [newCacheBehavior],
      origins: [googleOrigin],
    },
  },
});

If it's not supported at the moment, can we combine SST v3 (Pulumi) with CDK ? An example would be much appreciated.

I'll add an example for this but here's a snippet from somebody in Discord https://discord.com/channels/983865673656705025/1227658579046174872/1228260750695465001
